About Hydration Buddy: Water Tracker
Hydration Buddy is a calm, ADHD-friendly water companion. No shame, no streak pressure, just steady sips and gentle progress. YOUR BOTTLE DOES THE WORK Own a smart water bottle (like HidrateSpark) whose own companion app saves your drinks to Apple Health? Hydration Buddy counts them automatically by reading Apple Health. The app never pairs with or connects to any bottle. There is no hardware setup at all. No smart bottle? Logging by hand takes two taps. A GENTLE GAME, NOT A GUILT TRIP Earn points for pacing and consistency, not volume. Rewards stop at 150% of your chosen goal, and more water never earns more points. Miss a day? That's just a fresh start. A PRIVATE AI WATER BUDDY Ask about your patterns, the app, or general hydration ideas. Chat runs through Apple Intelligence on your iPhone by default. Prefer your own AI provider? Bring your own key, and it's stored only in your device Keychain. You choose exactly what hydration context is shared, with a byte-exact preview, and you can turn it off any time. The buddy never pushes you to drink more, and goal changes always require your explicit confirmation and can be undone. MADE FOR ADHD BRAINS Glanceable progress ring, two-tap logging, gentle check-ins that stay inside your active hours, and a home screen widget. No account required, ever. PRIVACY FIRST No developer server. No tracking across apps. Anonymous usage analytics show us which screens you open and that a drink was logged, never the amount. They never include Apple Health data, your goal or chat messages, and there are no screen recordings. Turn analytics off anytime in Settings. Health data never feeds ads or marketing and never leaves your iPhone except summaries you explicitly approve for your chosen AI provider. Full policy inside the app. HYDRATION BUDDY PLUS (optional subscription) Private iCloud sync of app-owned data, premium chat backgrounds and buddy themes, expanded history, ad-free. Core tracking, Apple Health sync and safety features are free forever. Hydration Buddy is not a medical device and gives no medical advice. Hydration needs differ from person to person, if you're unsure about a target, a clinician can help.
