Installing the APK
Download the file on your phone and tap it. Android will ask to allow installs from your browser ("Install unknown apps" → allow), and Play Protect may ask to scan it — "Install anyway" completes the install. This is normal for apps outside the Play Store; a Play Store release is planned.
