Drink Water!

Drink Water! is a simple app for logging the water you drink each day and getting reminders throughout the day, with no accounts, no ads and nothing sent off your phone.

The home screen is built for speed: one tap logs the amount you used last time. If you want something different today, switch between the sizes you have set up or type a custom amount with "Other amount…". A progress ring shows what you have drunk against your goal, and below it you will find today's records, which you can delete if you make a mistake.

Reminders are spread evenly between the start and end times you choose, with as many alerts as you like. They stop once you reach your goal, are recalculated every time you log water, and the home screen shows when the next one is due. They vibrate without making a sound, so your phone can stay in sound mode without being disturbed; if you wear a paired watch, the alert reaches it too. If you prefer, you can turn on skipping the reminder that would land right after you drink.

From the notification itself you can log your usual amount or snooze the alert for 15 minutes. There are also two home screen widgets, a 1x1 and a 2x1 that also shows today's progress. One tap logs your usual amount without opening the app.

At the end of the day you can get a summary notification (11:00 PM by default, with a configurable time, and you can turn it off) with what you drank against your goal. Each day in the history also opens a detail screen with its entries, where you can delete any you like.

History covers the last 30 days with each day's total, the average, your best day and your current streak. You can pick the language (automatic, Spanish or English) and the theme (automatic, light or dark), read what is new in each version inside the app, and email the author from Settings.

Your privacy: there are no accounts, no cloud, no ads and no tracking. Your records and settings are stored only on your device. The code is open source under the MIT license.
