About the F-Droid build
This build contains no Google services and no crash reporting. Sign in with your email and password; upgrading to a paid plan opens the web portal.

Switching from the Google Play version? The two are signed with different keys, so Android makes you uninstall one before installing the other, and uninstalling deletes the app's local data. Sync first: open the Outbox and make sure every change has been sent.

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
