Hydration, enforced
Most reminder apps send one notification and give up. HydraHound does not. After your chosen interval ends, the hunt starts immediately with clear 8-nudge rounds, escalating pressure, and optional Beast Mode if you want every lost day to sting.
Free 3-day trial then £9.99/year. Optional Beast Mode credit pack available inside the app.
Hound Mode
There is no extra reminder step and no grace period. Your chosen 30 minute or 1 hour interval runs silently, then the hunt begins immediately. Every round is exactly 8 nudges. Depending on difficulty, you lose the day after 8, 16, or 24 missed nudges.
Features
HydraHound is tuned to keep the rules simple enough that the app and notifications always agree about where you stand.
Your chosen interval runs silently, then Hound Mode starts right away. No grace window. No fake calm before the chaos.
Hard loses after 8 nudges, average after 16, easy after 24. Every hunt notification tells you exactly how close you are.
On-device AI writes fresh hounding copy so the app stays sharp without sending your data anywhere.
Every confirmed drink can be written to Apple Health automatically. Optional, local, and under your control.
Turn it on once and lost days start costing credits. You get 5 free to start, then buy another local 10-credit pack if you keep slipping.
No account required. No analytics. No ads. No backend. Your logs, credits, and reminder state stay on your device.
How it works
Choose your wake time, sleep time, and whether you want a 30 minute or 1 hour interval.
The blue button logs the drink, stops any active hounding, and resets the silent countdown.
When the interval ends, Hound Mode starts immediately. The app counts in clean 8-nudge rounds and shows your progress to a lost day.
Optional Beast Mode starts with 5 free credits. Lose a day, lose a credit. Run out, and HydraHound locks until you buy more.
Pricing
HydraHound Premium unlocks the app. Beast Mode is an optional add-on inside Premium, not a replacement for it.
No charge until the trial ends. Cancel any time from your iCloud Subscriptions. HydraHound never sees your payment details. Everything is handled by Apple.
Enable Beast Mode once inside the app and HydraHound gives you 5 free credits. Each lost day costs 1 credit. When you hit zero, the app locks until you buy more.
Credits are consumables stored only on your device. They do not restore after deleting the app or moving devices. Also, yes, some of this may end up spiritually supporting a Ferrari.
