Hydro: Water Tracker Reminder

Drink. Track. Repeat.

Hydro is a beautifully simple water tracker. Log every glass in one tap, watch your vessel fill through the day, and let gentle reminders keep you on pace — without ads, accounts, or subscriptions getting in the way.

💧 One-tap logging
Your favourite containers become quick-add buttons. Glass, can, bottle — or add your own sizes. Need a custom amount? A single slider handles it in seconds.

🔔 Log straight from the notification
Every reminder carries +250 ml and +500 ml buttons. Tap one and it's logged silently — you never even open the app.

🌙 Reminders that respect your sleep
Set your wake and sleep times and Hydro only nudges you in between. Already hit your goal? It stays quiet. Reminders are battery-friendly by design.

📊 See the habit build
- A month calendar where goal-met days fill with colour
- Weekly, monthly and yearly charts with daily averages
- A streak counter with one free freeze per week, for the day life gets in the way

🎨 Make it yours
Seven water colours, light and dark themes, millilitres or fluid ounces, and a home screen that stays clean.

🔒 Private by design
- No account and no sign-up — open the app and start
- Your log is stored only on your phone; nothing is uploaded
- No ads, no subscriptions, no in-app purchases — everything is free
- Export your complete history as CSV anytime
- Works fully offline

⚡ Small, fast, honest
Hydro asks for exactly two permissions: notifications (for reminders you control) and boot (so reminders survive a restart). That's it.
