Most health apps give you the same goals every day — drink 3L, walk 10K steps, sleep 8 hours. But your body doesn’t work like that. Hydra adapts your hydration based on your day — weather, activity, and lifestyle. It also connects water, sleep, and steps in one simple system so you can understand your habits better. Built to be fast, minimal, and privacy-first — no accounts, no data tracking, fully offline.
Hey Product Hunt 👋
I built Hydra because I was frustrated with health apps giving the same advice every single day.
“Drink 3L water”
“Walk 10,000 steps”
“Sleep 8 hours”
It never adapts to real life — like hotter days, more activity, or inconsistent routines.
So I built something that actually adjusts based on your day.
Hydra is designed to be:
• Simple enough to use daily
• Smart enough to adapt automatically
• Private (no accounts, no tracking)
Would love your honest feedback on:
1. Does the idea of “adaptive health goals” make sense?
2. Is combining water + sleep + steps useful or too much?
3. What would make you use this every day?
Happy to answer everything 🙌
