You can use one Gaia GPS account with multiple devices, or switch between Apple and Android devices, by logging into both of them. This will allow you to access your membership, tracks, routes, waypoints, and maps on all your devices.
To use Gaia GPS on another device:
2. When the app opens, select "Have an account? Sign in." or tap Settings > Account > Log in.
3. Use the same email and password (or Facebook login) you used on your previous device.
4. Once logged in, your information will start to sync. You can check when it has finished by tapping Settings > Account >. The date/time will appear next to "Last Sync" when it's complete.
