Hydration, enforced
Most reminder apps send a notification and give up. HydraHound doesn't. Miss a reminder and Hound Mode begins — escalating follow-ups until you drink.

Hound Mode
Ignore a reminder and HydraHound enters Hound Mode. Notifications arrive every few minutes — getting more direct, more insistent, more relentless. The only way out is to drink.
Features
Everything HydraHound does is in service of one goal: getting you to drink water.
Up to 10 escalating follow-up notifications per missed reminder. Spaced minutes apart. Getting louder.
On-device AI writes unique notification copy each cycle so it never feels repetitive. Runs entirely on your device.
Every confirmed drink is logged to Apple Health automatically. Your intake history, always up to date.
Set your wake and sleep times. Reminders stay within your active window and stop before you go to bed.
Track your drink history, hound count, average hounding duration, and your best and worst days.
No account required. No data leaves your device. No analytics, no ads, no tracking.
How it works
Tell HydraHound your wake time, sleep time, and whether you want hourly or half-hourly reminders. That's it.
A notification arrives on schedule. Tap the blue "I hydrated" button in the app and the clock resets.
Miss the reminder and HydraHound enters Hound Mode. Follow-up notifications begin, escalating in tone and frequency.
Tap "I hydrated" and everything resets. The hound stands down. For now.
