Drinking enough water shouldn't feel like a chore and tracking it shouldn't feel like a game. Hydrawell keeps it simple: tap to log, watch the ring fill, and trust that the number in the app is the same number in Apple Health. LOG IT IN ONE TAP Cup and Bottle presets handle the usual amounts or enter a custom number when you need something different. Either way, it's logged in seconds. YOUR WATER, ON YOUR WRIST Hydrawell's Apple Watch app logs and shows your progress right from your wrist, in step with your phone. Log on one, and both agree. You can even add today's total right to your watch face, so it's visible without opening anything. IT ACTUALLY TALKS TO APPLE HEALTH Every glass you log writes to Apple Health, and every entry you delete is removed from Health too — so your numbers never drift apart. Hydrawell isn't guessing at your hydration; it's the same data, everywhere. A GOAL THAT'S ACTUALLY YOURS Set a daily target that fits your life, not a generic recommendation, and watch a simple ring fill toward it over the day. A GENTLE STREAK, NOT A GUILT TRIP See how many days in a row you've hit your goal on a simple month calendar (solid color for a day you hit goal, a soft tint for a day you logged something but fell short). Today never breaks your streak just because it isn't over yet. MAKE IT YOURS Eight color themes and your choice of ounces or milliliters. Every theme is tuned for dark mode as well as light, not just left to the system default. Small touches without clutter. RIGHT AT HOME ON ANY SCREEN Built to fit an iPhone SE without feeling cramped, and just as sharp stretched across a full iPad. GENUINELY FREE No subscription, no trial, no paywall, no ads. Hydrawell is just built to help you drink more water. Hydrawell. Your water, on your wrist, in your Health app.
