Install
- Download the APK on an Android phone.
- Open it. Android will ask to allow installs from this browser — accept once.
- Launch OPEN and create an account.
- Go Open, then join the demo space code to see other people.
Android 12 or newer. Bluetooth is used to notice nearby phones; the app
asks for no location permission at all.
What it does
- Open — a state that always expires on its own.
- Open Here — how many people nearby are open, never who.
- People Open — minimal profiles, no name, no photo, no distance.
- Say Hi → Accept — nothing identifiable before two yeses.
Internal trial. Not a public release.
