Two ways in.
Install it, sign in with Google, and your conversations are yours across reinstalls.
Install the app
The build is finished and in testing — biometric unlock, the camera in the composer, and all five rooms. The download goes up here the moment sign-in is working on the device.
Tell me when it is readyAndroid 8.0 and above.
Before you install
Android 8.0 or newer, a Google account to sign in with, and about 40 MB free. Everything else — the five rooms, the reasoning test, the app lock — is in the build.
Read the FAQNo Play Store account required.
Installing the APK
Tap the download, open the file, and allow your browser to install apps when Android asks. That prompt appears because the app is not coming from the Play Store — it is the same permission you would grant to any direct download.
What is different on Android
Fingerprint and face unlock use the phone's own authenticator, the camera opens natively in the composer, and haptics are real taps rather than the browser's approximation.
