Rillwick tracks water, tea and coffee with a filling glass, a simple history, and a caffeine clock. It works fully offline.
Where is my data? Only on your device. Deleting the app or using Settings, Erase everything, removes it. There is no cloud copy.
Can I change the goal or units? Yes. In Settings pick millilitres or fluid ounces, enter your weight for a suggested goal, or set your own goal.
I did not get reminders. Turn on Gentle reminders in Settings and allow notifications for Rillwick in iOS Settings. Reminders stay quiet outside your chosen hours and after you reach your goal.
I logged a drink by mistake. Tap Undo on the confirmation, or open History and edit or delete the entry.
