Installing on Android

The apps aren’t in Google Play yet, so Android asks a couple of extra questions the first time.

  1. Open this page on the phone (scan the QR code) and press Download.
  2. When the download finishes, open it. If Android says it can’t install apps from this source, press Settings, turn on Allow from this source (“install unknown apps”) for your browser or file manager, and go back.
  3. Press Install. You may see a warning that the app is from an unknown developer or a Play Protect check: that is expected for an app from outside Google Play. Choose Install anyway (under More details on some phones).
  4. Open the app and sign in with your GT account. To update later, download the new version here and install it over the old one.

Only install the apps from this page. The SHA-256 under each download lets you check the file is exactly the one we published.
