Quick answer
Lock the screen
F-Droid repository metadata
Very fast shortcut to lock the screen (just launch the app).
Realized for FAST launcher to be able to lock the screen searching for "lk" app (it will isolate this app as the only one containing "l" and "k" in its name).
How to install
- Download the APK from the button at the top of this page.
- Allow “Install unknown apps” for your browser or file manager only, not for every app.
- Open the downloaded file and confirm the installation.
- If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.
Data safety
- Every file is checked against its published SHA-256 before it is listed.
- Files are scanned for malware on every update.
- The permissions each app requests are listed on its own page.
- Read the full safety policy for how we test, flag, and delist files.
