• One-tap drink sizes: choose up to six. Your default stays on the big Add button, and up to five more sit in a row right above it, on iPhone and Apple Watch. • New Undo button next to Add takes back your last drink. • Change your sizes anytime in Settings.
I was looking for a simple water tracker. One that let me open the app, tap a button to add my drink, and get back to my life. What I found were apps filled with ads, cluttered dashboards, and constant pressure to buy a subscription. I wanted a tool, not a chore. So I built Biru. Biru is the water tracker I always wanted. It's built on one core idea: tracking your water should be fast, simple, and completely frustration-free. WHY BIRU IS DIFFERENT • NO CLUTTER, PURE FOCUS Your day is a single rising wave. Your total sits in the middle and inverts as the water covers it. That's the whole screen — nothing else gets in your way. • GET IN, GET OUT, GET HYDRATED Log a drink with one tap. Set up to three quick-add sizes to match the bottles and glasses you actually use, in millilitres or fluid ounces. You're done in seconds. • NO ADS. NO SUBSCRIPTIONS. NO PAYWALLS. Every feature in Biru is free, forever. There's an optional tip jar if you'd like to support development, but it unlocks nothing — the app is already complete without it. • ON YOUR WRIST Biru comes with a full Apple Watch app. Log a drink without your phone, pick another size, or check your week. Add a complication to any watch face — the large one shows the same rising water as the app. • ON YOUR HOME SCREEN Five widget styles in small and medium. Tap a size to log it without opening the app, or see your last seven days at a glance. Press and hold any widget to choose which sizes it offers. • A SIMPLE, SMART START Answer a few quick questions and Biru suggests a personal daily goal based on your weight, age, activity and climate. It's a starting point, not a rule — adjust it whenever you like. • OPTIONAL APPLE HEALTH SYNC Turn Health on and your drinks are saved alongside the rest of your data. Leave it off and Biru works exactly the same. • BUILT IN THE OPEN Biru has a roadmap inside the app. Suggest a feature, report a bug, vote on what matters to you, and see what's coming next. If you've been searching for a water tracker that respects your time and your focus, your search is over.
