Water Reminder makes it effortless to stay hydrated every day. Set a personal daily goal based on your weight, track every sip with one tap, and watch an animated water-fill bottle rise as you progress toward your target. Getting started takes seconds. Enter your weight and Water Reminder automatically calculates the right amount of water for your body. Choose to track in millilitres or fluid ounces — whichever feels natural to you. Adding intake is instant. Tap a quick-add button for a standard cup, mug, or water bottle, or enter a custom amount. Each drink is logged with a timestamp and saved to your daily history. Six drink types are supported — water, tea, coffee, juice, sports drink, and milk — so your log reflects what you actually consume. A beautiful animated bottle fills in real time, giving you a satisfying visual cue of your progress. Glance at it any time to see exactly how close you are to your goal. The History tab shows a monthly calendar with coloured indicators for days you hit your goal, plus a streak counter that rewards consistency. Swift Charts display your weekly intake as a bar chart so you can spot patterns and stay on track. Interval reminders nudge you to drink at regular intervals you choose. Set a reminder every hour, every two hours, or at a custom interval — Water Reminder will send a gentle notification so you never forget. No account. No subscription. Just a clean, focused hydration companion that helps you build a healthier habit one glass at a time.
