One app for the whole building.
Open the front door, invite friends, book the rooftop and pay rent from one app. No fobs, no paper forms, no guessing which portal.
Daily life, without the friction.
The small moments the app quietly removes.
Today:A fob you cannot lose, until you do, and a replacement fee.
Hold your phone to the reader. Lost phone? Your building team revokes and reissues in seconds.
Today:Come down to let them in, or prop the door.
Send a visitor pass from the app. It works for the hours you choose, then expires on its own.
Today:An email to the building manager and a wait.
See what is free and book it, right next to your door key in the app.
Today:A bank transfer to remember and a receipt to chase.
See what is due and what was paid, with receipts issued automatically.
The modules you live in.
Four modules power the app.
Access control
Your phone is the key, for every door your lease covers.
See the moduleVisitors
Guest passes that expire on their own.
See the moduleAmenities & bookings
The gym, rooftop or meeting room in a few taps.
See the moduleRent & payments
Rent, receipts and what is due, in the same app.
See the moduleWhat it feels like day to day.
The building works the way your phone already does.
Move-in day is about moving
ID, lease and door access are sorted before you arrive, not in a folder of forms.
One app, not four portals
Entry, visitors, bookings and rent in one place, signed in once.
A lost phone is a non-event
Access is revoked and reissued in seconds, not rekeyed over days.
Answers without back and forth
Your building team sees the same record you do, so questions get sorted first time.
Your data, handled properly.
The same governance that protects the operator protects you.
Stored in Australia
Your data lives on Microsoft Azure with Australian data residency.
Biometrics under the Privacy Act
Where biometric entry is offered, handling is aligned to the Privacy Act and OAIC guidance.
Entries are facts, not guesses
Building access is recorded on a governed trail, which protects residents too: who came in, and when, is never a matter of opinion.
Want this in your building?
BTR OS reaches residents through the building operator. If your building could use it, the person to ask is your operator or building manager.
