Mayim is a calm water tracker and drink reminder. Log a glass in one tap, see what is left for today, and let the reminders go quiet once you hit your goal. One tap and it counts A big cup button in the middle of the screen. Tap it, the ring fills with a small wave, move on. Tapped by mistake? Undo. Type any amount you like, in ml or oz. With Premium, a mug, a bottle, a large bottle and your own custom cups are one tap away too. A widget that does the work Add a glass right from the home screen widget, without opening the app. Lock screen widgets show the ring, what is left today and when the next reminder lands. On your wrist and by voice The Apple Watch app logs a glass with one tap and keeps counting when your iPhone is out of reach. Complications put today's ring, what is left and your streak on the watch face. Ask Siri to log a glass or how much you drank today, or use Shortcuts and Spotlight. On iPhones that support Apple Intelligence, Mayim writes a short recap of your week on the iPhone itself and never sends it anywhere. A daily goal made for you Enter your weight and activity level and Mayim suggests a sensible daily water goal. Or skip that and pick a number. On hot days, nudge it up. Reminders that stop at your goal Choose your waking hours and how often to be reminded. Reached your goal? Reminders go quiet until tomorrow. Smart reminders (Premium) also hold back while you are ahead of pace, instead of buzzing on schedule. Streaks and history See how many days in a row you hit your goal, and your week at a glance. Premium adds your full history, the month view and stats such as your record day. Private by design Your water log stays on your phone. No account, no ads, and it works offline. Light and dark mode included. Free and genuinely useful Full tracking with any amount, the ring widget in every size, standard reminders, 7 days of history, the Apple Watch app and Siri. Premium: one purchase, no subscription Every widget style, one-tap mug, bottle, large bottle and custom cups, your full history and stats, and smart reminders. Pay once and it is yours.
