Back up your log and move it to another phone.
Settings now has Back up log, which saves every site, extinguisher, service record, signature and tag into one file, and Restore from backup to load that file onto another device. Records merge by ID, so nothing already on the phone is deleted. Photos are optional, so the file stays small enough to email.
Also fixed: a fast double tap on a photo button could close the app, and a few screens could close twice.
