Which file do I need?
Universal APK
Works on almost every device. If you're unsure, install this one.
arm64-v8a APK
A smaller, per-ABI build for modern 64-bit phones.
.aab (App Bundle)
This is for Play Store upload only — it is not directly installable on a phone. Use an APK to sideload.
Source code
Build it yourself or inspect every line — the full project is on GitHub under the MIT license.
Before you install
Only install builds from a source you trust. Open Lock's release APKs are signed in CI, so you can verify the package id and signature against the GitHub Release. Sideloading may require enabling "install unknown apps" for your browser or file manager.
