Sync note: changes save to the cloud instantly and reach your other devices on their next sync. If the phone app has unsynced local changes, the phone's copy wins when it syncs — open the app and sync it before editing here. GOV is entered manually on the web for now; on calibrated vessels the app computes it from the tank tables.
