How Water Buddy works
Built for people who spend long hours at a computer and forget to stay hydrated.
Pick Your Goal & Interval
Enter your body weight or set a custom goal (like 2.5 Liters). Pick how often you want reminders, such as every 30 or 45 minutes.
A Cute Character Walks In
At your set interval, an animated buddy strolls across the bottom of your screen and asks: 'Did you drink water?'. It never steals your typing focus.
One-Click Logging
Click 'Yes' (+150ml or +250ml) or 'No'. Your buddy reacts with cheerful animations, your daily tray progress ring fills up, and you stay healthy.
Find your recommended water goal
Calculate ideal daily hydration calibrated for your body weight, height, and health routine.
Built specifically for Windows
