Tap the drop. That's it. Water Reminder is the simplest way to drink enough water every day. Tap the drop to add a glass, hold it for more, and watch it fill up as your day goes on. You can also add water from a widget or your Apple Watch. No ads. No sign-up. No subscriptions. Just water. WHAT YOU CAN DO - One tap to add: tap the drop for a glass, hold it to add several at once, or type in any amount. You decide how much a glass holds. - Widgets: see today's water on your Home Screen and Lock Screen, and tap a widget to add a glass without opening the app. - Apple Watch: add a glass from your wrist, pick any amount with the Digital Crown and check your streak. Put your progress on your watch face, and Water Reminder comes forward on your watch around each reminder. - Reminders on your schedule: choose your hours and how often, set different weekend hours, and reminders stop once you reach your goal. They count from your last drink, so they won't nag you right after one. - Your own daily goal: in millilitres or fluid ounces, change it anytime. - Your history, day by day: see every day at a glance and open any day for details. - A streak to keep you going: reach your daily goal and watch your streak grow, day after day. If it's at risk, you get a heads-up while there's still time. - Quiet by design: no accounts, no clutter, and your log stays on your device. WHY IT HELPS Staying hydrated supports your focus, energy and overall wellbeing. Water Reminder keeps it effortless: a gentle nudge when it's time, and one tap when you drink.

The hydration tracker you never open. Waterd uses Apple Intelligence on supported devices to set your daily water goal based on your activity, the weather, and how you've been hydrating this week — automatically, on-device, no cloud. On devices without Apple Intelligence, Waterd uses a built-in formula based on your weight, activity, and weather forecast. Then it gets out of your way. Tap your bottle from the Home Screen widget, the Lock Screen, the Dynamic Island, your Apple Watch, or a notification action. Each tap is one drink, logged in under five seconds. The app exists for weekly reflection, not daily logging.
