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.
