Truly Smart

Unlike basic timers, our reminders factor in your activity, caffeine intake, and progress. More active? You'll get reminded more often. Already ahead of your goal? We ease off.

Science-Backed Goals

Your daily water goal isn't a guess. It's calculated from your weight, age, sex, and activity level using established hydration research.

Caffeine Aware

Coffee and tea count, but not equally. We track caffeine's diuretic effect and adjust your effective hydration accordingly.

Motivation Built In

Streaks, XP, levels, and 12 unlockable achievements keep you coming back. Hydration becomes a game you actually want to win.

Apple Watch Native

A full companion app on your wrist. Log drinks, check progress, and get reminders without touching your phone.

Privacy First

Zero data collection. No accounts. No analytics. No ads. Everything stays on your device, protected by iOS encryption.

What Sets Us Apart

Most hydration apps are just glorified timers. Here's how Water Reminder+ is different.

Adaptive Reminders

Other apps remind you every X minutes regardless of what you're doing. Water Reminder+ uses a 4-factor algorithm (activity, caffeine, progress, time of day) to send reminders when you actually need them.

Caffeine Hydration Factor

A cup of coffee isn't the same as a glass of water. We apply hydration factors to different beverages so your "effective hydration" reflects reality.

Gamification That Works

XP, levels (Seedling to Hydration Master), streaks, and achievements create a feedback loop that turns a daily chore into a rewarding habit.

Completely Offline

No account required. No internet needed. The app works entirely offline with local data storage. Your health data never leaves your device.

Beautiful. Intuitive. Effective.
