Drink more water. Joe makes it easy.
Joe fills up as you do. Log water, coffee or tea with one tap and Drink as Joe works out how much each one really hydrated you. Reminders come when you need them.


Small habits. Big difference.
For iPhone with iOS 26, Apple Watch optional. In six languages, English included.
48 drinks
Water, coffee, tea and more. Each drink has its own hydration factor, so you know how much it really counted.
Smart daily goal
A goal based on your profile. A hot day, a workout or feeling unwell raises it with one tap.
Smart reminders
Nudges when you need them, not every hour. Log water straight from the notification.
Challenges and streaks
Hydration Hero, Caffeine Detox or a sugar-free week. Streaks keep you going.
23 characters
Joe and his friends, unlocked with streaks and challenges. They all fill up with water.
Watch and widgets
