Waterline

A personal drink log for iPhone and iPad.

Set a daily goal, add quick actions for your bottles and cups, and log water, coffee, tea, soda, or other drinks. See the last seven days in milliliters or US fluid ounces. The Lock Screen widget shows progress and logs a drink.

Optional Apple Health sharing

Enable Water writing in Settings to send entries marked Water to Apple Health. Other drinks count only toward your local goal. Widget entries save immediately and sync to Health when you next open the app. Waterline does not read Health data or send your log to Roscommon Group.

Seven days free

Log free for seven days. Then unlock app and widget logging with a one-time US$9.99 purchase, or the local price shown by Apple. No subscription. Entries stay readable after the trial. Restore with the same Apple Account.

Waterline is a personal record, not medical advice or a recommendation for how much water you should drink. Available for invited TestFlight testers.
