About this app
Struggling to drink enough water? Cactus is the water tracker that gently helps you build a daily hydration habit. 💧
Cactus is a simple and beautiful water tracker for your daily hydration. Set a personalized daily goal, log every drink in seconds, and watch your cactus grow each day you hit your water intake target. No accounts, no sign-up — just open and start.
PERSONALIZED DAILY HYDRATION GOAL
Get a recommended water goal based on your weight, activity level, and climate. Or set a custom daily intake target. The hydration calculator adapts to you, not a one-size-fits-all formula.
LOG DRINKS WITH ONE TAP
Glass, water bottle, mug — log a drink in seconds with your favorite containers. Supports ml, oz, and gallons. Custom container library — add your 1L sport bottle once, tap to log forever.
GENTLE HYDRATION REMINDERS
Smart water reminders throughout the day at the right intervals. Set quiet hours so you're not buzzed at 3 AM. Choose sound, vibration, or silent push.
NOT JUST WATER
Track coffee, tea, juice, sparkling water too. Cactus calculates the net hydration contribution automatically based on each drink type. Caffeine intake tracked separately.
A GROWING CACTUS 🌵
Stay consistent and your cactus grows. Unlock new species — desert bloom, prickly pear, golden barrel. Visual progress you can show off. Streaks reward daily hydration without being annoying.
HEALTH INTEGRATION
Syncs with Apple Health and Google Fit. Daily, weekly, monthly statistics. See your average water intake trend over time.
PRIVACY FIRST — FREE FOREVER
No account required. No data collection. Everything stays on your phone.
Drink water. Grow your cactus. Stay healthy.
