For aquarium keepers
Keep tank care visible without turning it into a spreadsheet.
Free users can manage one tank, log readings without a limit, and see the last 30 days in trend charts. A one-time unlock adds full-history trends, additional tanks, and new care or inventory records. Users with water readings before 1.3 keep full-history trends. Widgets, Siri, Shortcuts, existing records, and existing reminders remain available to free users.
