Start here

Getting started

New to the app? Start with these.

You can be surveying within five minutes. The app works fully without an account.

  1. Install the app from the App Store or Google Play and open it. A short welcome tour runs once, then the app asks you to pick your region. That sets spelling, units and currency.
  2. Add your company details. Tap “Settings” (the gear, bottom right), stay on “Profile”, fill in “Company Details” and tap “Save Company Details”. A company name is needed before you can start a survey, and these details print on every report.
  3. Start a survey. On the home screen tap “Start New Survey” (or the round + button). Read the “Surveyor Responsibility” note and tap “I Agree & Continue”.
  4. Work through the survey cards. The survey opens on its dashboard. Start with “Survey Details” (client, address, dates), then add rooms, photos and readings. Only fill in the cards that apply to the property.
  5. Check the report. Tap “Generate Report” to see the finished report. Read it through, fix anything in the preview, then tap “Save”.
  6. Send it. Tap “Share” to save or send the PDF. See Save or send the PDF.

For a fuller walk-through with pictures, read Getting started. On the app's home screen, “How to complete your first survey” opens a short guide inside the app.

DampApp Pro is free to download and use. You can build complete surveys, preview the report and share the PDF without paying. Pro is an optional subscription for people who survey often or want their own branding.

Free reports carry a small Produced with DampApp Pro™ footer. Prices are on the pricing section. To upgrade, see Upgrade to Pro.

Where to find it:SettingsProfileRegion & Language

Pick your country under “Select Region”. The app then matches it everywhere:

  • Spelling and terms, for example mould or mold, in the app and in the PDF.
  • Currency for costs. You can override it in Settings if you prefer a different one.
  • Temperature in °C or °F.
  • Tax label on your company details (VAT, ABN, GST and so on).
  • AI wording, so AI Polish and the summary write in your regional English.

Where to find it:SettingsProfileText Size

Free for everyone, in app version 1.11.0 and later.

  1. Open “Settings” and stay on “Profile”.
  2. Under “Text Size”, tap “Match my phone” to use the text size set on your phone, or tap a size from “Smaller” to “Largest”.
  3. The app changes straight away. Tap another size if it does not suit you.
  • Match my phone is where the app starts. On an iPhone or iPad, the phone's size is in Settings → Display & Brightness → Text Size. On Android it is usually Settings → Display → Font size.
  • Very large phone sizes are shown at the app's “Largest”, so every screen still fits.
  • Only the words in the app change. Your reports, the report preview and the PDF your client gets stay the same.
  • The size is saved on each device, so your phone and tablet can be different.

Where to find it:SettingsProfileTips

The first time you reach a new feature, a short tip explains it. Tap “How it works” to see the steps in the app, with a button to open this help page. Only one tip shows at a time.

  • Tap “Got it” to hide a tip. It also goes once you use that feature.
  • Tap the “?” beside a feature's name at any time to see how it works.
  • To stop tips, turn off “Tips” in Settings → Profile. “Show all tips again” brings back every tip you have hidden.
  • Tips are saved on each device.

You never need a signal to survey. Rooms, photos, readings, floor plans, signatures and the finished PDF all work offline.

These need a connection: live weather, the UK EPC lookup, soil data, the AI tools and cloud sync. If you are offline, tap them again once you have signal. Only cloud sync retries by itself.

Cloud sync PRO: when you are signed in with Pro, each survey backs up automatically and appears on your other devices. Tap the cloud icon on the home screen, or “Sync Now” in SettingsSharing, to sync straight away.

Editing one survey on two devices

Sync keeps the most recently saved copy of each survey as a whole. If you edit the same survey on two devices while offline, the older edits are replaced. Finish a survey on one device at a time.

Tap the sun, moon or screen icon at the top of the home screen to switch between light and dark. The app starts by following your phone's setting; once you tap the icon it keeps the look you chose.

Reports and PDFs always show in light mode, so they print and read the same for your client.

Updates come through the App Store or Google Play, like any other app. Turning on automatic updates for your phone keeps you on the latest version.

  • After an update, a “What's New” message may appear once. Tap “Got it, thanks!” to close it.
  • Your version number is at the bottom of SettingsHelp & Legal. Please include it if you contact support.
  • Updating never deletes your surveys.

Pro, subscriptions & billing

What Pro adds, how to upgrade, and how to restore or cancel it.

  1. On the home screen, tap the “GET PRO” badge at the top. Tapping any feature marked Pro also works.
  2. Choose monthly or yearly. If a free trial is offered, the button says so.
  3. Confirm with Face ID, your fingerprint or your store password. You pay Apple or Google, not us.
  4. You will see “Welcome to Pro!”. Pro features unlock straight away on this device.

Pro belongs to the Apple ID or Google account that bought it. To use it on another phone or tablet, see Restore Pro on a new or reset device. Then sign in to bring your surveys across (Sign in, sign out and reset your password).

If you have paid for Pro but the app shows the free version, restore your purchase. It is free and does not charge you again.

  1. Make sure the phone is signed in to the same Apple ID or Google account you used to buy Pro.
  2. Tap “GET PRO” on the home screen, then tap “Restore”.
  3. Or go to SettingsHelp & LegalManage subscription and choose “Subscription & billing”.

If you see “No previous purchase found to restore.”, the phone is probably signed in to a different store account, or the subscription has ended. Check in your store account (links in Manage or cancel your subscription).

Pro and your app login are separate

Pro follows your App Store or Google Play account. Your DampApp Pro login is what brings your surveys across. On a new phone you usually do both: restore Pro, then sign in.

Where to find it:SettingsHelp & LegalManage subscription

This shows your plan and lets you change or cancel it. Apple or Google handle the billing, so cancelling happens in your store account:

Deleting the app does not cancel

Uninstalling DampApp Pro does not stop the subscription. Cancel in your store account, as above. Refunds are handled by Apple or Google.

When Pro ends: your surveys stay on the phone. If you have more than 25, you can still open them, but you cannot start a new survey until you are within the free limit of 25. Cloud backups are deleted 30 days after Pro ends, so export anything you need first (Back up or move surveys with a JSON file).

Account, devices & data

Signing in, moving to a new phone, backups and deleting surveys.

Where to find it:SettingsSharingLogin / Register

Signing in is part of Pro. It backs up your surveys and lets you open them on another device. Free users can use the app fully without an account.

  1. Tap “Login / Register”.
  2. Choose “Sign in with Google”, “Sign in with Apple”, or an email and password. For a new email account, tap “Sign Up”. The password needs at least 8 characters, including a capital letter and a number.

Forgotten password: on the sign-in screen tap “Forgot Password?”, enter your email and tap “Send Reset Link”. Check your inbox (and spam folder) for the link.

Sign out: SettingsSharingSign Out. Signing out does not cancel Pro.

With Pro:

  1. Install DampApp Pro on the new device.
  2. Restore Pro: tap “GET PRO”, then “Restore”.
  3. Sign in with the same account as before: SettingsSharingLogin / Register. Your surveys and photos download.

On Free:

  1. On the old phone go to SettingsSharing and tap “Mass Export (JSON)”. Save the file somewhere you can reach from the new phone, such as email or cloud storage.
  2. On the new phone go to SettingsSharing, tap “Import Survey Data (JSON)”, tick “Survey Records” and “Company Profile”, and choose the file.

Photos do not travel in a Free export

A JSON file carries the survey text and readings, not the photos. Share the finished PDFs from the old phone first if you need the photos.

Free monthly allowances (AI and Smart Build) are counted on each device.

  • On your phone: every survey is saved on the device first. On Free that is the only copy, so deleting the app deletes those surveys. Export a backup now and then (JSON backup).
  • In the cloud PRO: when you are signed in with Pro, surveys and photos are also backed up securely and can be restored on another device.
  • Limits: Free stores up to 25 surveys on the device; Pro up to 5,000. To make room, export or delete finished surveys.
  • If Pro ends: cloud backups are deleted after 30 days. Accounts not used for 365 days are also removed.

The full policy is in SettingsSharing under “Cloud Data Retention Policy”, and in SettingsHelp & LegalStorage Limits & Quotas.

You are responsible for your clients' personal data in your surveys (you are the data controller). Delete surveys you no longer need to keep.

A JSON file is a backup copy of your survey data that you can keep on a computer or load into the app again.

  • Back up everything: SettingsSharingMass Export (JSON).
  • Back up one survey: open its report, tap the “i” button, then “Download”.
  • Load a backup: SettingsSharingImport Survey Data (JSON). Tick “Survey Records”, “Company Profile” or both, then choose the file. Importing a Company Profile replaces your current company details.
  • Pro also has an import button on the home screen.

Photos: without Pro cloud sync, photos are not included. With Pro, the file holds secure links to your cloud photos, so they come back when you import.

Where to find it:HomeRecent Surveys

  • Search: type in “Search surveys...” to find a client name, address or reference.
  • Filter by date: use the dropdown beside the search box (All Time, Past 7 Days, Past 30 Days and so on).
  • Delete one: tap the bin icon on the survey's card and confirm.
  • Delete several: tap the tick-box icon by the survey count, choose the surveys, then delete.
  • Delete by age: tap the grey bin icon by the survey count. Check the option before tapping “Delete Now”: it starts on “Every Single Survey In System”. Choose, for example, “Older than 90 Days” instead.

Deleting is permanent

With Pro cloud sync on, deleting on your phone also deletes the cloud copy. Export anything important first.

So that no survey is forgotten, the home screen flags drafts that have been left unfinished:

  • A badge such as “Unfinished 4 days” appears on the card. It turns amber after 3 days and red after 6.
  • A line above the list counts your drafts in progress and how many have been waiting a long time.
  • The app sends a reminder on your phone 48 hours after you last saved an unfinished survey. Nothing is sent over the internet.

Finish the report with “Generate Report”, or delete the survey, and the badge and reminder go away.

Where to find it:SettingsSharingDanger ZoneDelete Account

This option shows only while you are signed in. Tap “Delete Account”, then “Yes, Delete Permanently”. It erases your login and everything backed up in the cloud. It cannot be undone.

You can also delete your account from a computer on the delete account page.

This does not cancel Pro

Cancel your subscription in your App Store or Google Play account as well (how to cancel).

On a computer, go to the export page and sign in with your DampApp Pro account. You can download all your synced surveys, or one at a time, as a ZIP file containing the survey data and full-size photos. Keep the window open while it builds; large accounts take a minute or two.

This is for backups and record keeping. The formatted PDF reports are made in the app.

Where to find it:SettingsHelp & LegalContribute anonymised insights

When you first use the app it asks once whether you would like to help build industry benchmarks. It is optional, and you can switch it off at any time with the toggle above.

  • What is shared: the type of damp found, its severity (low, medium or high), the indicator tags you approved, whether a meter reading was taken, and your country.
  • What is not: names, addresses, client details, photos and your report wording.
  • A pseudonymous counter used to stop abuse is kept for up to three days and is never published.

Trends are published on prosurvey.app (opens in a new tab) only once enough surveys are included to keep them anonymous.

Building your survey

Each section of a survey, in the order you are likely to use them.

Where to find it:Homea finished surveyStart follow-up visitor the same button at the bottom of the report

Going back to a property? Start a follow-up visit instead of a new survey, so you do not type the same details twice.

  1. On the home screen, find the finished survey and tap “Start follow-up visit”.
  2. The app makes a new draft dated today, with the same reference plus -V2 (then -V3, and so on).
  3. Work through the survey as usual. Under each reading you see what it was last time, so you can record what you find today.
  • Copied across: the client and property details, rooms and outside areas, the floor plan, fans, wall build-ups, the planning check and your report wording. Wall readings grids come back with the same walls, heights and positions, ready for new readings.
  • Starts empty: readings, damp types, photos, observations, recommendations and the signature.
  • A banner at the top shows which visit this is and the date of the last one.
  • The report and PDF say Follow-up visit 2 under the title and name the previous visit's date and reference.

Changes since last visit PRO: the report and PDF add a section showing each room's readings then and now, with up, down or no change in words, and before-and-after photos. Rooms you did not revisit are left out, and new rooms are marked New.

The follow-up is its own survey. Deleting the earlier one keeps the comparison table but removes its photos from it.

Wherever you see “Add Room Photos” or a camera icon, tap it and choose:

  • “Take Photo” to use the camera.
  • “Photo Gallery” to pick up to 10 photos you have already taken.
  • “Browse Files” for photos saved in Files or a cloud drive.

The first time, your phone asks for permission to use the camera or photos. Tap Allow. If you said no by mistake, turn it on in your phone's Settings app under DampApp Pro.

Tap a photo once it is added to give it a caption or mark it up (Photo captions and markup). Pro can stamp the date and time on photos (Photo timestamps).

Where to find it:Open a surveyRoom Analysis or External Analysistap a photo

  1. Tap any room or outside photo to open it full size. Just after you add a photo, a “Photo added. Mark it up?” bar shows for a few seconds: tap “Mark up” to open that photo straight away (it stays hidden when tips are turned off in Settings).
  2. Caption (free): type or dictate a short note about what the photo shows.
  3. Markup PRO: tap “Circle”, “Arrow”, “Draw” or “Label”, pick red, yellow or white, and drag on the photo. “Undo” takes off the last mark and “Clear” takes them all off.
  4. Tap “Save”. The “X” at the top and the phone's Back button save too; “Cancel” leaves without saving.

Once any photo in a room or area has a caption, the report numbers that room's photos and prints the captions under them, such as Photo 2: Tide mark 600mm above the skirting, so your written findings can refer to them. Rooms with no captions look exactly as before.

Your markup is drawn over the photo, not saved into it, so the original photo is kept untouched as your evidence. If you stop paying for Pro, markup you already added still shows in the report, and you can remove it.

Where to find it:Open a surveyRoom AnalysisAdd Room

Add one entry for each room you inspect, then record what you found:

  • Moisture readings from your meter for walls, floors or spots you tested.
  • Photos using “Add Room Photos”: a wide shot for context plus close-ups of each defect.
  • Observations in your own words. Type, dictate with the microphone, or tidy them with AI Polish.
  • Surface temperature and dew point for condensation risk in that room.

Tap “Analyze Images with AI” for a suggested description of a photo (AI Polish and photo analysis).

To record readings at several heights along a wall, use Moisture readings up the wall.

Where to find it:Open a surveyRoom Analysisa roomWall readings

Record a set of meter readings for a wall, at several heights and positions, and the report shows them as a table after the room's photos, observations and recommendations.

  1. Tap “Add a wall” and pick a name such as North wall or Party wall, or type your own.
  2. Type each reading into the grid. The highest height is at the top, like the wall itself. Each reading shades as you type: dry, at risk or wet.
  3. Tap “Edit heights and positions” to add, remove or change heights, or to give positions a label and a distance along the wall.
  • “Scale and shading” sets the meter scale name (WME % to start with) and the levels for at risk and wet, so it works with your own meter.
  • Add notes under each wall, and switch “Show in report” off to leave a wall out.
  • Heights and positions with no readings are left out of the report. The app shades the readings but never names a cause; that is your judgement.

Wall readings are part of Pro. Readings already on a survey always show in the report.

Where to find it:Open a surveyExternal AnalysisAdd External Area

The outside of a building is often where damp starts. Add each area you inspect, such as the front or rear elevation, and record defects like cracked render, blocked gutters or a bridged damp-proof course, with photos of each.

“Analyze Images with AI” suggests a description of a photo. Free includes 3 uses a month; Pro can use it daily. Always check what it says against what you saw.

Where to find it:Open a surveyPsychrometrics

Enter the air temperature, relative humidity and surface temperature for one reading outside and one inside. The app works out the dew point and tells you whether the surface is at risk of condensation. The figures go into the report and the AI summary.

Readings for individual rooms and walls go in Room Analysis and External Analysis.

Where to find it:Open a surveyCondensation & U-value

Checks whether moisture could condense inside a wall, roof or floor, not just on its surface.

  1. Tap “Wall”, “Roof” or “Floor” to add a construction.
  2. Add its layers from the inside out, choosing from 30 standard materials, and set each thickness.
  3. Tap “Use property location” to use local climate data. Without a signal it uses the nearest of 63 built-in locations.

The U-value updates as you go. The result is one of: no risk, dries out within the year, or moisture builds up. Tap any month to see the classic Glaser diagram. Tick “Include in report” to add it to the PDF, and add your own comment underneath.

A screening check

This uses the standard steady-state (Glaser) method. It ignores rain, air leaks and moisture moving through the material, so treat it as a comparison. Unusual or borderline constructions need a specialist hygrothermal assessment (BS EN 15026).

Where to find it:Open a surveyFloor Plan

Choose “Draw Plan” to draw it yourself, “Upload Image” to use an existing plan, or “Scan a room with AR” PRO to scan it.

Drawing:

  • Draw walls; they snap to each other and to square angles.
  • Trace a room to get its floor area in m² or ft².
  • Place doors and windows on the walls.
  • Set the scale by drawing along something you have measured, such as a door, and typing its length.
  • Drop damp markers and photo pins to show where each problem is.

AR scanning PRO needs an iPhone or iPad with LiDAR (Pro models) on iOS 16 or later. In the editor tap “Scan a room”, name the room and walk around it slowly. Scan more rooms and each one appears beside the last; drag its “Move room” tab to slide it into place. On other devices the scan option does not appear, and you draw instead.

Tap “Save” (with the tick) to add the plan and its key to the report. The ⋮ menu has “Export as PDF” for the plan on its own.

Check key measurements

Scans are a fast starting point, not a measured survey. Measure anything important by hand.

Where to find it:Open a surveyWeather & OrientationFetch Weather

Weather affects damp readings, so the report records it. With Pro, tap “Fetch Weather” and the app fills in the temperature, humidity, wind and conditions at the property's address. If the survey date is in the past, it looks up the weather for that date instead.

  • Daily limit: weather comes through our shared service, with a daily limit on each device. To remove it, add your own weather key.
  • Rain radar: the small map shows rain from the last two hours. It can run about ten minutes behind, and shows nothing when it is dry, which is correct.
  • Your own readings: you can type or correct every value, for example from your own hygrometer.

Where to find it:Open a surveySoil & Drainage

Ground conditions help explain rising damp and water penetration.

  1. Tap “Set Location” to put the pin on the property's address, or tap the map to drop the pin yourself.
  2. Tap “Fetch Soil Data for Pin Location”.
  • The app looks up clay, sand and silt levels, pH and more from ISRIC's global SoilGrids database, then works out the soil type and how well it drains.
  • Choose a depth layer to see the ground below foundation level.
  • The soil database can be slow, so give the lookup a little time.
  • In built-up areas the app searches outwards for the nearest soil data. If none exists nearby, it says so.

If enabled, the report includes the soil figures, your notes and the map.

Where to find it:Open a surveyPlanning & Constraints

Find out in one tap whether the property is listed, in a conservation area or in a flood zone, from the public registers for where it is.

  1. Fill in the address in Survey Details first.
  2. Tap “Check this address”. Each result shows where it came from, with a link to the register entry.
  3. If the address lands in the wrong place, tap “Move the pin”, put the pin on the building and check again.
  4. Add anything else you know in “Your notes”, such as what the council told you.
  • Where it works: England, Wales, Scotland, Northern Ireland and the United States. It follows your region in SettingsProfileRegion & Language, and is hidden where there is no public register to check.
  • What it checks: listed buildings, conservation areas and flood zones in England, Wales and Scotland, plus scheduled monuments and World Heritage Sites. England also has tree preservation orders and Article 4 directions. Northern Ireland covers listed buildings and scheduled zones. In the US it checks the National Register of Historic Places and FEMA flood zones.
  • Not covered by open data: the screen and the report say what to check yourself and where, for example Northern Ireland's flood maps, or a US city's own historic districts.
  • Listed buildings are mostly recorded as a single point, so the check looks 30 metres around the address and says so.
  • The report and PDF show each result, your notes, the date of the check and the registers used. Untick “Include in report” to keep it out.

This is not a legal search. Registers can be out of date or incomplete, so confirm anything important with the local planning authority.

Where to find it:Open a surveyEnergy Performance Certificate (EPC)

  • UK lookup PRO: tap “Fetch UK EPC Data”. The app uses the address from Survey Details to find the property on the government register and fills in the ratings, floor area and expiry date.
  • Other countries: choose your country's scheme (Ireland BER, US HERS, Australia NABERS and more than ten others) and pick the ratings by tapping the scale. The report draws the right chart for that scheme.
  • Recommendations: you can add energy-saving recommendations in their own box.

To leave EPC out of reports, turn it off in SettingsProfilePDF CustomizationVisible Narrative Sections PRO.

Where to find it:Open a surveyHHSRS Scoring(switch it on in SettingsProfileHHSRS Scoring)

Scores hazards using the official HHSRS formula, as amended in 2026.

  1. Add only the hazards you judge to be present. Quick buttons cover damp and mould, excess cold, fire and falls; “Other…” has all 21.
  2. Set the likelihood of harm over the next 12 months on the slider.
  3. Split the likely harm across the four outcome classes so they add up to 100%. The buttons help with this.

The score, band and category update as you go. A score of 1,000 or more is a Category 1 hazard. Link the rooms where you saw evidence, add notes, and the report shows each hazard clearly.

Your judgement, the official formula

The app never suggests a likelihood or harm split; it only does the sums. Enforcement decisions rest with the local authority.

Where to find it:SettingsProfileCompliance Timeline

Shows target dates for each stage of a repair, so follow-ups are not left to memory. Once switched on, it appears in each survey's “Survey Details”, under the dates.

  • Presets: Awaab's Law, damp & mould, Awaab's Law, emergency hazard, and a general example to edit to your own policy. Change the stages and days in “Configure stages & presets”, and lock them with your PIN if you like.
  • Start date: choose which date in the survey the timeline counts from, or enter the date the tenant reported the problem.
  • Colour coding: each stage shows on track, due soon or overdue, with days left.
  • Reminders: turn them on to get a phone notification as each date approaches. They stop when the survey is completed or deleted.

A planning aid, not legal advice

The dates are indicative. In England, Awaab's Law applies to social housing and is being phased in. In Scotland, it applies to social and private landlords from 6 October 2026, for damp and mould. Both count working days, while the app counts calendar days from the date you choose, so set the stages to your own policy. The free Scotland timeline calculator works out the working-day dates. Always check the current rules and your organisation's policy.

Where to find it:Open a surveySurvey DetailsResident summary letteror the letter button at the top of the report screen

A short, plain-English letter for the household, drafted from your survey in one tap. It covers what you inspected, what you found, the landlord's planned dates when the Compliance Timeline is on, and simple tips when condensation or mould was found.

  1. Tap “Resident summary letter”. The app drafts the letter.
  2. Add the resident's name if you know it. Left blank, the letter starts Dear Resident.
  3. Change anything you like. Under the letter, “Smart Build” adds ready-written paragraphs above the sign-off, such as next steps, advice on mould, health and extra help. “AI Polish” makes the wording clear and friendly without changing the facts.
  4. Tap “Share PDF”. The PDF carries your logo and signature.

At the top of the PDF, a box shows the resident's name and the address on the left, and the date and your reference on the right. They come from the survey, so they always match the report.

Your changes are saved with the survey. “Start again from the survey” gives you a fresh draft. Readings are left out on purpose, and the letter says it is a summary, not the full report.

Where to find it:Open a surveyReport NarrativeVentilationExtractor Fans

Log each extractor fan: where it is, what type, and whether it works. Each fan can also have a Part F check:

  1. Choose the room type: kitchen, utility room, bathroom or WC. The app shows the minimum extract rate from Approved Document F (England).
  2. Enter the rate you measured with an anemometer, or the fan's rated figure, in litres per second.
  3. The app says whether it meets the minimum and, if not, suggests what to do next.

The result appears under the fan in the report. The figures are a guide; check them against the current Approved Document F, or local rules outside England.

Where to find it:HomeAd-Hoc IAQ Assessment

A quick check for one or more rooms without starting a full survey, for example on a callback visit.

  1. Add each room with its name and orientation.
  2. Enter the air temperature, humidity and surface temperature, and add a photo if you like.
  3. The app gives each room a status score. Tap “Download Report” or “Send via Email” for a short report.

Where to find it:Open a surveySurvey DetailsProperty Age / Construction Era

Choose “Pre-1919 (traditional / solid wall)” for older buildings. The AI then favours advice suited to breathable traditional materials such as lime and timber.

Where to find it:Open a surveyEssential Costs

  • “Load Standard Items” adds common jobs from six groups: damp proofing, timber treatment, ventilation, external maintenance, external surveys and inspections, and internal works.
  • “Add Custom Cost Item” adds anything else, with your own description and price.

The report totals them in a table, in your region's currency.

Where to find it:SettingsProfilePhoto Timestamp Overlay

With Pro, the date and time are printed on your survey photos automatically, as a dated record of what you saw. It is on by default; switch it off with the toggle above.

“Photo Timestamp Source” chooses which time is used: when the photo was originally taken, or when you added it to the survey.

Where to find it:Open a surveySurvey DetailsReport Type / Title

Pick a ready-made title, or tap “Add Custom Title” and type your own. The app remembers it for next time. To remove a saved title, tap the bin icon next to it in the same list.

AI & smart tools

Tools that write or tidy report wording for you. You always check the result.

  • Free: 3 free uses of each AI tool every month (AI Polish, photo analysis, the summary, its translation and Talk through a room). Before you use one, the app shows how many are left and asks you to confirm with “Use 1 Free”. They reset on the 1st of each month, and are counted on each device.
  • Pro: AI works every day through our built-in service, up to a daily limit.
  • Pro with your own key: no limit from us. You pay Google or OpenAI directly, usually a few pence a day. See Set up your own AI key.

If you see “AI Limit Reached” or “Daily AI Limit Reached”, look it up in Troubleshooting.

AI Polish turns rough notes into professional wording. Type or dictate a note, then tap “AI Polish” (it has a sparkle icon) under the box. It is on almost every text box: room and area findings, wall notes, photo captions, checklist notes and the report's editable text, where it shows once you tap into a box. It also works on your default report wording in Settings PRO.

You type: damp patch on ceiling corner, needs checking above, maybe roof leakAI Polish gives: Evidence of isolated moisture ingress was noted to the ceiling corner. Further investigation of the roof covering above is recommended to determine the source.

Where it is relevant, the wording refers to the standard that applies in your region, such as BS 5250 or Approved Document F.

Photo analysis: in a room or external area, tap “Analyze Images with AI”. The AI suggests a description of the defect and tags what it can see, such as tide marks, mould or efflorescence. If a moisture meter is in the photo, it reads the value. You can switch each tag on or off, and the confidence score is never shown to your client.

Always check AI output

AI can be wrong. Treat every result as a draft and correct it against what you saw on site.

How many uses you get: How much AI can I use?

Where to find it:Open a surveyReport Narrativeany sectionSmart Build

Smart Build (the magic-wand button) fills a section from a few quick choices, using standard wording for common findings such as condensation, rising damp or poor ventilation. It is standard template text, not AI. Edit the result to fit the property.

It is also under the smaller boxes that have standard wording: room and area observations and recommendations, wall notes and photo captions, where it adds to the end of what you have typed, and beside a wall's name, where it builds a name such as Ground floor rear wall, north facing.

  • Free: Smart Build on a few reports each month. Once a report has used it, that report keeps it. Smart Build shows how many you have left.
  • Pro: every report, and your default report wording in Settings.
  • Smart Build for your company introduction and disclaimer in Settings is always free.

For surveys set to Saudi Arabia, the UAE or Qatar you can add an Arabic translation of the executive summary; for India, a Hindi one. Elsewhere the button does not appear.

  1. Tap “Generate Report” and scroll to the executive summary.
  2. Tap “Generate Arabic summary” or “Generate Hindi summary”.

The translation appears under the English summary in the report and the PDF, right to left for Arabic. It uses one of your AI uses (allowances). If you can, have someone who reads the language check it before it goes out.

Tap the microphone under a text box (on the larger report sections it sits in the box's top corner) and speak. Your words appear as you talk and are added after anything already in the box, so nothing is overwritten. Tap it again when you have finished.

  • Your phone asks for microphone permission the first time.
  • Dictation uses your phone's own speech recognition (Apple or Google), which may process the audio on their servers.
  • Tap “AI Polish” afterwards to turn spoken notes into report wording.

Where to find it:Open a surveya room or outside areaTalk through this room

Say what you see and the readings you took, and AI sorts your words into the right boxes for you to check.

  1. Tap “Talk through this room” (or “Talk through this area” outside) and speak. Your words appear as you talk. Tap Stop, then fix any misheard word or type instead.
  2. Tap “Fill in the room”. Under “Check before it goes in” you see only the boxes you spoke about, each with a tick. A box that already has words offers to add to the end or replace.
  3. Untick anything you don't want, then tap “Apply selected”. Nothing changes until you do.
  • It can fill the damp type (only when you name it), temperature, humidity, surface temperature, observations, moisture readings and recommendations.
  • Free includes 3 a month. Pro uses it daily, or without our limit using your own AI key.
  • It needs an internet connection. If the AI can't be reached, your words are kept and “Add my words to Observations” puts them in as spoken.

Where to find it:SettingsProfileRegion & LanguageStandards & regulations for your region

A plain-English list of the standards and legal duties for your region, grouped by topic. For the UK that includes HHSRS, Awaab's Law, BS 5250, BS 8102 and Approved Document F. Each entry explains the key points and links to the official source. It updates without an app update.

These are the same standards the AI refers to in your report wording.

Reports: preview, branding & sharing

Where to find it:Open a surveyGenerate Report

  1. Tap “Generate Report”. The report opens exactly as your client will see it, and the survey is marked Complete.
  2. Read it through: names, dates, photos, findings and recommendations. You can correct text in the preview.
  3. Tap “Save”. The “Share” button (and the email button, if you have set up email) appears once everything is saved.

Completed surveys open straight to the report from the home screen.

In the report, tap “Share”. Your phone's share menu opens with the PDF, so you can:

  • save it to Files, iCloud Drive, Google Drive or OneDrive;
  • send it by your email app, WhatsApp or Teams;
  • print it to a wireless printer.

Sharing is free. On Free, the first time you may see a note that the report carries the DampApp Pro™ footer, with “Continue” or “Add my logo”.

To send straight from the app under your own email address, see Email reports from your own address.

Where to find it:SettingsSharingSMTP Settings

This sends reports from the app using your own work email, so they reach clients from you. You need a few details from your email provider.

  1. Switch “Custom SMTP” on.
  2. Fill in “SMTP Host” (for example smtp.gmail.com or smtp.office365.com), and choose “SSL” (port 465) or “TLS” (port 587).
  3. Enter your full email address as the “Username”, your password, and the name and address clients should see.
  4. Tap “Save”, then “Test”.

Then, in a saved report, tap the envelope icon, choose “My Email” or “Client Email” and tap “Send”.

Two pieces of standard wording are set once and used in every report:

  • “Company History / About Us”: a short introduction to your business.
  • “Independent Surveyor Disclaimer”: your standard independence statement.

Smart Build can draft either one for you, free.

Default report wording PRO: on the same screen, tap “Edit Report Wording” to set the text every new survey starts with, such as “Scope of Survey”, “Technical Definitions” and “Damp Methodology”.

  1. Pick a section.
  2. Type your own wording, or tap “Smart Build”, choose the options that fit your usual jobs and tap “Use Generated Text”.
  3. To tidy wording you typed, tap “AI Polish” under the text.
  4. Read it through and tap “Save”.

Surveys you have already started keep their own wording, which you edit under “Report Narrative”. From app version 1.11.0, default report wording is part of Pro. If you saved some on the free plan before then, your new surveys still start with it.

Tap the gear at the bottom right. Settings has four tabs:

  • Profile: your company details, logo PRO, region, text size, tips, default report wording PRO, report look PRO, photo timestamps, HHSRS and the Compliance Timeline.
  • Integrations PRO: your own AI and weather keys (guide).
  • Sharing: sign-in and sync, email (SMTP), JSON import and export, and deleting your account.
  • Help & Legal: contact support, manage your subscription, privacy choices and the app version.

Memberships: in Profile, switch on “PCA Number” or “CIOB / RICS Number” and type your number. It prints as text on the report; logos of professional bodies are not added.

Your own AI and weather keys

For Pro, and recommended. The app works without them, but only up to our daily limits; your own keys remove those limits.

We recommend adding your own key. The AI tools work without one, but only up to our daily limit. Your own key removes that limit, and you pay Google directly for what you use, usually a few pence a day.

Gemini now needs billing switched on

Google's free allowance is now too small for everyday survey work. Set up prepaid billing in Google AI Studio and add a monthly spend cap. The guide shows exactly how, with a cap so you are never surprised by a bill.

Open the step-by-step Gemini guide →

In short: create a key at Google AI Studio (opens in a new tab), set up billing with a spend cap, then in the app go to SettingsIntegrationsGoogle Gemini, paste it into “Google Gemini API Key” and tap “Save & Sync Settings”.

Not sure whether to use Gemini or OpenAI? Compare them here.

ChatGPT Plus does not include this

The OpenAI key is billed separately from any ChatGPT subscription. You buy prepaid credit (from US$5) on OpenAI's developer site. With no credit, the key does not work.

Open the step-by-step OpenAI guide →

In short: at platform.openai.com (opens in a new tab) buy credit, switch off auto recharge, set a monthly limit, then create a key. In the app go to SettingsIntegrationsOpenAI, paste it into “OpenAI API Key”, leave “OpenAI Model” on “Automatic (newest GPT mini)” and tap “Save & Sync Settings”.

Recommended. Pro fetches weather without a key, but only up to a daily limit. Your own OpenWeatherMap key removes that limit, and their starter plan normally covers survey use at no cost.

Open the step-by-step weather key guide →

Ignore the paid subscriptions

Older instructions, including ours, said to subscribe to OpenWeatherMap's “One Call 3.0” with a card. You do not need it: the key from sign-up is enough for live weather. Leave the second box, “OWM Maps 2.0 API Key (Overlays)”, empty unless you already pay for Weather Maps 2.0.
