About this app

Water tracker with drink reminders and AI. Log any beverage, keep each other on track with friends, and drink water every day. Free to start.

Stay hydrated. Feel better. Live healthier.
Most people forget to drink water, and it shows in their energy, focus, skin, and mood. Waltermelon is the water tracker and drink reminder app built for real life: smart, social, and genuinely fun to use.

💧 The Water Tracker That Actually Sticks
Log every drink in seconds. Track water intake, hydration streaks, and daily goals in one water tracker and hydration tracker app designed to keep you coming back. No more forgotten days.

⏰ Smart Drink Reminders That Work
Your water reminder shouldn't feel like spam. Waltermelon sends a smart water reminder based on your wake time, sleep schedule, and daily hydration goal. Get a gentle drink water reminder when you actually need one, not when you're asleep. It's the hydration reminder your future self will thank you for.

🤖 AI Beverage Recognition
Can't find your drink? Just type it. Our AI recognises hydration levels, caffeine, alcohol, and more. Craft cocktail, builder's tea, or homemade smoothie, Walter handles it in seconds. No searching, no guessing.

⚡ AI Quick Intake
Just describe what you drank and the AI handles the rest. "A mug of builder's tea" or "a pint of orange juice", Walter understands and logs it in seconds.

🎯 Daily Challenges & Rewards
Small hydration tasks, new every day: log your drinks, hydrate before a set time, hit your goal. Each challenge earns 10 to 25 Drops, and finishing them all opens a chest of rewards.

🛡️ Rescue Shield
Every day you hit your water goal, your hydration streak grows. Missed a day? Spend Drops on a Rescue Shield and your streak stays. You decide when to use it, and the calendar shows the days it saved.

👫 Drink Water with Friends
Add friends, see how their day is going, and send a cheer or a nudge in one tap. Start a shared hydration challenge: pick a type and a length, and if the group makes it, everyone gets Drops. The reward grows with every person and every day. Invite a friend and earn Drops once they log their first drink.

📱 Home Screen Widget
Log water without opening the app. Add the Waltermelon water tracker widget to your Android home screen and add a drink in one tap.

🍵 Built for British Drinks
Tea, squash, cordial, fizzy drinks, sparkling water. Waltermelon's drink library covers UK favourites. Add your own custom drinks too.
