For landlords, letting agents & short‑let hosts
The evidence app for people who let property.
The Witnessed app runs inventories, check-ins and check-outs room by room, keeps every certificate and deadline in one place, and seals every photo with an independent timestamp, so any later edit or backdating shows.
Free to try: 3 sealed certificates a month, and a whole inspection report counts as one. No account, no sign-in.
The problem
Letting runs on records.
When a deposit is disputed, a certificate lapses or a repair drags on, what counts is what you can show, and when you recorded it.
Deposit disputes are decided on evidence
An adjudicator can only go on what’s in front of them. Usually that means the landlord or agent has to show the condition at check-in, the condition at check-out, and why the difference is more than fair wear and tear. Vague notes and undated photos make that hard.
Compliance has a lot of moving parts
Gas Safety every year, electrical checks every few years, deposits protected within tight time limits, the right documents served at the right time. The rules differ across England, Wales, Scotland and Northern Ireland, and they keep changing.
A photo on its own proves very little
The date and location on an ordinary photo can be changed in seconds with free software, and convincing images can now be generated from a sentence. Anyone on the other side of a dispute knows it.
How it works
Add. Inspect. Seal.
Set a property up once. Every inspection, certificate and repair after that builds on it.
Step one
Add the property
Rooms, tenancies or guest stays, deposit details and certificates. Witnessed works out what’s due and when, and puts it on your home screen.
Step two
Inspect room by room
Checklists built from the property’s own rooms. Rate condition and cleanliness in a tap, add notes, photos and video to each item, record meters, keys and alarms, and take signatures on screen. Photos are sealed as you go.

Step three
Seal one report
One tap produces a PDF report with its own fingerprint and timestamp, ready for a tenant, a client or a deposit scheme. A check-out is compared with the check-in, item by item, with any proposed charges.
Features
Everything a let needs, in one place.
Built around how UK lettings actually work, from a single flat to a portfolio of holiday lets.
Compliance & deadlines
Nothing lapses without you knowing.
Add a certificate once and Witnessed works out when it expires, then reminds you before it does. Deadlines from tenancies, guest stays and repairs land in the same list.
- Gas Safety, EICR, EPC, deposit protection, prescribed information, How to Rent, Right to Rent, HMO licences, fire risk, legionella, PAT testing, insurance and more
- Deposit protection and prescribed information deadlines for new tenancies
- Check-outs flagged as a tenancy comes to an end
- The 14-day damage claim window after a short-let guest checks out
- A repair log with response timelines for damp, mould and other hazards, and a dated timeline of every step
Guidance only. Requirements differ across England, Wales, Scotland and Northern Ireland, and short-let platforms set their own claim rules, so check what applies to you.
Your portfolio
Find anything. Hand over everything.
Search every property, tenant, inspection, document, repair and piece of evidence at once. When someone needs the record, export it in a form they can check without the app.
- Properties with rooms, tenancies and guest stays, and a home screen of what needs attention next
- Evidence packs: a ZIP with the original files, their timestamp tokens and a plain-English guide to checking them
- CSV export of your evidence log, for a spreadsheet
- Designed for iPhone and iPad, so the same record works on site and at the desk
Rapid capture
Keep shooting through a room while each photo is sealed in the background, switching the room or item it’s filed under as you go.
Photo, video, audio & scans
Seal video walk-throughs, audio recordings and multi-page document scans as well as photos, each with its own certificate.
Signatures tied to the record
A signature is bound to exactly what the tenant or contractor was shown. Change a rating or a photo afterwards and it no longer matches.
Works offline
No signal in the basement flat? Capture anyway. Timestamps are requested automatically as soon as you’re back online.
Private iCloud backup
Optional. Back up and restore through your own private iCloud. Witnessed has no server holding your data and can’t see your files.
Face ID & passcode lock
Lock the app with Face ID, Touch ID or a passcode just for Witnessed, and hide its contents in the app switcher.
Sealed evidence
What a seal records.
Every photo, video, recording, scan and inspection report gets a certificate. The fingerprint and the timestamp are cryptographic, and anyone can check them.
Anyone can check it
No app, no account, no need to trust us.
Every certificate PDF carries a QR code that opens witnessed.uk/verify. The check runs in the browser, so the file isn’t uploaded anywhere.
- Drop in the original file and its timestamp token from the evidence pack.
- The fingerprint is recalculated from the file’s exact bytes.
- The authority’s signature is checked against the token. Standard tools like OpenSSL work too.
Who it’s for
Made for people who let property.
Tell Witnessed how you’ll use it when you set up, and the quick actions on its home screen follow suit.
Landlords
One flat or fifty. Inventories and check-ins you’ll be glad of at the end of the tenancy, certificates that don’t quietly lapse, and a dated record of every repair.
Letting agents
Managing homes for clients. Consistent room-by-room reports signed on the day, and compliance dates for every property you look after, in one search.
Short-let & holiday-let hosts
Turnover inspections between guests, each stay tracked, and a reminder before the 14-day damage claim window after checkout closes.
Tenants & tradespeople
Tenants can document a new home on moving day. Tradespeople can record a job before and after, and have it signed off on site.

Why you can trust it
The technical bit, in plain English.
Witnessed doesn’t ask you to take its word for anything. The parts that matter can be checked by someone who has never heard of us.
A fingerprint of the exact file
Each file is run through a one-way function that produces a 64-character fingerprint. Alter a single pixel and the fingerprint changes completely. It reveals nothing about the picture and can’t be turned back into it.
A clock that isn’t yours
The fingerprint is sent to an independent timestamp authority, which signs it together with the time. DigiCert is tried first, with Sectigo and FreeTSA as fallbacks. RFC 3161 is a long-established international standard, the same kind of timestamp used on signed software and signed PDFs.
Context, recorded honestly
Your phone records when, on what device and, if you allow it, where each capture was made. That context sits alongside the certificate for reference; the authority’s signature covers the fingerprint and the time. Photos imported from your library are labelled as imported.
Your records stay yours
Properties, inspections and evidence are stored on your iPhone or iPad. iCloud backup is optional and goes to your own private iCloud. The only thing sent for sealing is the fingerprint, never the file.
Checking a certificate doesn’t depend on Witnessed staying in business: the file, its token and standard tools are enough. Witnessed gives you a record of what you captured and when. It isn’t legal advice, and how evidence is weighed is always up to the adjudicator or court.

Questions
Before you start.
Do I need an account?
No. There’s no sign-up, no password and no email address to hand over. Everything is stored on your device, with optional backup to your own private iCloud.
What counts as one certificate?
One sealed photo, video, audio recording or document scan is one certificate. A whole inspection is also one: every photo in it plus the sealed report. It’s counted when you start the inspection.
Will a deposit scheme, insurer or court accept it?
No app can promise that, and we won’t. What Witnessed gives you is dated, detailed evidence where any change to a sealed file can be detected by anyone who checks it.
How evidence is weighed is always up to the adjudicator or court, and nothing on this site is legal advice.
Does the compliance guidance cover Scotland, Wales and Northern Ireland?
The certificate types, suggested expiry dates and deadlines are general guidance, and many of them follow the rules in England. Requirements differ across the UK and change over time, so check what applies to your property and adjust dates to match. Every date can be edited.
Does it work without a signal?
Yes. You can inspect and capture offline. Items wait as pending and are timestamped automatically once you’re back online.
Can someone check a certificate without the app?
Yes. Send them the evidence pack. They can drop the original file and its timestamp token into witnessed.uk/verify, which runs in their browser and uploads nothing, or use standard tools such as OpenSSL.

Start the record before you need it.
A proper check-in costs nothing to have in place, and there’s no going back to make one after the tenancy ends.
