Why You'll Love It
Visual Hydration Tracking
A unique water container shows your daily progress in real time. Every drink you log changes the color — from tangerine (dehydrated) to azure (fully hydrated). See your health improve cup by cup.
Squad Up for Accountability
Create or join a hydration squad. Send encouraging messages, cheer each other on, and keep everyone accountable. Drinking alone is hard — drinking together is fun.
Earn Life Days
Hit your daily water goal to earn "life days." Stack them up, unlock medals from Long-Lived Mortal all the way to Life Origin Progenitor, and watch your projected lifespan grow.
Smart Reminders
Customizable notifications remind you to drink at the right times. Set your schedule, pick your sound, and build a healthy hydration habit that sticks.
Your Drinks, Your Way
Log water, tea, coffee, milk, beer, or spirits. Each tracks water content, caffeine, and alcohol automatically. Your daily target adjusts based on your weight, age, and alcohol intake.
Urine Color Calendar
A monthly color grid shows your hydration trends at a glance. Spot patterns, improve habits, and aim for those azure streaks.
