Get your deposit back—together.
Your deposit was never yours alone. rm8tes gives your flat one shared vault: GPS-tagged, timestamped photos from everyone who lives there, mirrored move-in to move-out, sealed into a single evidence pack the whole household owns.
> 3 flatmates connected…
Household · New
The people you live with are in this with you
Four people sign one tenancy and then document it on four phones that never speak to each other—so at move-out there are four half-stories and one landlord picking between them. rm8tes now gives your tenancy a household: one vault, shared by everyone in the flat, that any of you can add to and none of you can close alone.
You hand out a join code. They type it in. From that second you are documenting the same flat, on the same record, in each other’s company.
-
Invite
One code, and they’re in
Set up the flat and you get a short join code. Read it out over the kitchen table, text it, stick it on the fridge. Your flatmate types it in and lands in the same vault—no accounts to link, no invite lost in an inbox.
-
Together
Everyone shoots, everyone sees
Photograph your own room; open the app and see theirs. Each photo is credited to the flatmate who took it, and the flat leaves with one evidence pack covering all of it—not four partial ones that contradict each other.
-
Agree
Nobody seals alone
Sealing an audit is one-way, so in a shared flat every other flatmate has to agree it is finished first. No one can close move-out before you have photographed the damage in your room—and if the owner ever overrides that, the pack says so in writing.
-
Live
It lands while you’re looking
A flatmate’s photo, diary entry or sign-off appears on your phone as it happens. The boiler that broke in March is one repair history the household keeps together, written by whoever was home.
Credited, not named. Inside the evidence pack every photo carries a code for the flatmate who took it—so a landlord can see the same person shot the whole kitchen, without being handed a list of who lives where. The code is different in every property, and once someone deletes their account nobody can trace it back to them at all. How that works · what your flatmates can see.
And this is the first step, not the last. Renting with people is the part of renting nobody has built for. We started with the deposit because that is the part that costs you money—but a shared vault is where rm8tes stops being an app for renting from someone and starts being an app for living with someone. More of that is coming.

Evidence · How it works
You shouldn’t have to trust us
Anyone can call their photos tamper-proof. The question a deposit scheme actually asks is harder: could this have been changed afterwards? Here is how rm8tes answers that—and how you can check the answer without taking our word for any of it.
-
01
Fingerprinted as you shoot
The moment you take a photo, your phone computes its SHA‑256 fingerprint—a 64‑character code that changes completely if so much as one pixel moves.
-
02
Checked, not just claimed
Our server recomputes that fingerprint from the file it actually received, and rejects the record if the two disagree. A fingerprint the app alone decides is worth nothing—a tampered app would simply send whatever suited it.
-
03
Locked, then sealed
Once stored, a photo cannot be edited, swapped or quietly retaken. Finish your move-in and that whole set seals shut; move-out seals the same way—and in a shared flat, only once every other flatmate has agreed it is complete. That is what stops “move-in photos” appearing months into a dispute—usually the first thing a landlord will suggest.
-
04
Anchored to Bitcoin
Roughly once an hour we fold every new record’s fingerprint into a single code and timestamp it into the Bitcoin blockchain using OpenTimestamps, a free and open-source standard. Once that block is mined the code is fixed in a public ledger nobody controls—not your landlord, and not us.
✓ Check it yourself
Your evidence pack prints every fingerprint in full, the steps linking your photo to its Bitcoin timestamp, and instructions for confirming them with free, open-source tools. Those tools talk to the public timestamp servers and to Bitcoin directly—they never contact rm8tes. If we altered one of your records, the check would fail, and you would be the one holding the proof.
Where the line is. This proves your photos existed, exactly as they are, before a particular Bitcoin block was mined, and that nobody has changed them since—us included. It cannot prove what a camera was pointed at, and a phone’s clock is set by whoever owns the phone, so your pack shows our server’s timestamp as the one that carries weight and labels the device’s own clock as context. We would rather tell you where that line sits than have a landlord’s solicitor find it for you.
