Your data lives on your device
Every set is saved on your phone first, so Grain Gym works without a signal. An account is only for backup.
Use Grain Gym on more than one device
01Read
Every set starts on the device where you log it. Settings has a Sync screen, but sync between devices isn't available yet, so a backup is how you move your record.
Moving to a new phone
- On the old phone, go to Settings, then Backup & Restore. Tap Back Up to Account if you're signed in, or Export My Data for a JSON file.
- Install Grain Gym on the new phone. If you used an account backup, sign in with the same account.
- Go to Settings, then Backup & Restore, and restore the backup.
- Check your history before you remove anything from the old phone.
Using two phones
Each phone keeps its own record. A restore replaces the local data the backup covers, so export the phone you're restoring onto first if it has sessions you want to keep.
My numbers don't match across devices covers what to do when two phones disagree.
