Water Reminder: Drink Water

Water Reminder helps you drink enough water through the day, with reminders spaced across your waking hours.

WORKS COMPLETELY OFFLINE
Everything runs on your phone. No account, no sign-in, no server. Your log never leaves the device.

A GOAL THAT FITS YOU
Your daily target is worked out from your body weight, how active your day is, and whether you live somewhere hot. You can also set it by hand at any time.

REMINDERS THAT RESPECT YOUR DAY
Choose when you wake and when you go to bed. Reminders are spread evenly between the two and stop before bedtime, so nothing wakes you up. They survive a restart.

SEE PROGRESS AT A GLANCE
The ring fills as you drink, and its colour changes through the day — from "time to drink" to "goal reached". Today's log lets you correct a mis-tap.

HISTORY THAT MEANS SOMETHING
Seven and thirty day charts, your daily average, and how many days in a row you have hit your goal.

MADE FOR EVERYONE
Twenty languages. Millilitres or fluid ounces. 12-hour or 24-hour clock, whichever you prefer.

PRIVACY
The app itself collects nothing and has no server. Ads come from Google AdMob, which uses your device's advertising ID; you can reset or limit it in Android settings, and the one-time purchase removes ads for good. No sensitive permissions are requested — no location, no contacts, no camera, no files.

Water Reminder is not a medical device and does not replace professional advice. Talk to a healthcare professional about your own fluid needs.

Water Reminder works out how much water you need from your weight, how active your day is and whether you live somewhere hot, then spreads reminders across your waking hours and stops before bedtime.
