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.
