Thirsty Day

Meet Thirsty 3.0: a calm, futuristic hydration companion with luminous glass, a daily rhythm view, and animals full of personality. FREE EVERYDAY HYDRATION Log water, set a manual goal, build streaks, manage household profiles, use widgets, and choose optional reminders. Start with Otter and earn Cat, Dog, Fox, and Lion with logging streaks. Basic Apple Health water syncing and available health metrics remain free with your permission. OPTIONAL THIRSTY PRO — ONE-TIME PURCHASE Unlock all classic animals and adaptive guidance that combines local weather and workout/activity information to adjust your suggested goal as your day changes. Guidance refreshes while you use the app; weather and Health permissions are optional. No subscription. Verified pre-3.0 customers retain their existing adaptive guidance; existing Pro owners keep Pro access. CHOOSE YOUR COMPANION Unlock a favorite animal individually with a one-time purchase, or choose a collection. Individual companions are US $0.99; the App Store displays your local price. Pro includes the classic animals. The separate Mythic Creatures collection includes all six original fantasy companions. Already earned or owned animals never need to be bought again. Purchases can be restored. PRIVATE BY DESIGN No advertising. Health data is used for your hydration experience, not sold. Weather uses approximate location with permission. Kids profiles use their own manual goals rather than adult activity or heat adjustments. Hydration guidance is an estimate, not medical advice. Follow your clinician's advice, especially if you have fluid restrictions.
