Drink water. Prove it. Feel the difference.
Hydrater is a hydration companion that reminds you at the right moments, lets you verify drinks with a quick photo (or log without one), and shows you honest insights computed from your own history.
How it works
- Personalized reminders — a science-based daily goal (with safety ceilings) spread across your waking hours, pausing around meals.
- Photo verification — snap your full container, drink at your own pace, snap it empty. On-device AI checks it; your photos never leave your phone.
- Humane by design — mute, defer, partial credit, and photo-free logging are always available. No shame mechanics.
- Honest insights — your weekly chart and hydration score come from your real data, free for everyone.

Hydrater is in development for iOS and Android. The free version includes every feature, supported by a handful of ads; a one-time purchase removes them forever.
Losing 1–2% of your body's water can measurably affect mood, energy, and how effortful tasks feel — often before you notice you're thirsty (Ganio et al. 2011; Armstrong et al. 2012, British Journal of Nutrition).
Hydrater is not medical advice. If you have a kidney, heart, or liver condition, or take diuretics, ask your doctor about the right fluid target for you.
