Meet Bubbl — the water tracking app that gives you a reason to actually drink water. Your fish lives in your phone. When you stay hydrated, it swims happily around its tank, unlocks new friends, and shows off its custom colors. When you forget to drink? It flops dramatically on the sand and judges you. TRACK YOUR WATER YOUR WAY Log water in seconds with quick-tap presets, custom amounts, or our AI bottle scanner — just point your camera at any water bottle and Bubbl identifies it and logs the exact amount automatically. A FISH THAT NEEDS YOU Your fish reacts to everything. It spins when you log water, flops when you’re dehydrated, blinks lazily when it’s bored, and swims freely around its tank. Tap it and it’ll spin for you. It’s alive. Don’t let it down. UNLOCK A WHOLE SCHOOL Build your streak and unlock 10 unique sea creatures — from your starter pufferfish, clownfish, and angelfish all the way to a shark, octopus, jellyfish, seahorse, starfish, swordfish, and manatee. Each one is fully customizable with your own color combinations. COMPETE WITH FRIENDS Add friends, track each other’s streaks on the leaderboard, and send taunts when they fall behind. Nothing motivates hydration like a little competition. BUILT FOR REAL LIFE ∙ AI-powered bottle scanner identifies your water bottle automatically ∙ Daily streak system keeps you coming back ∙ Custom hydration goals in oz or liters ∙ Push notification reminders ∙ Dark and light mode ∙ Designed for all ages with full COPPA compliance for younger users Drink water. Keep your fish happy. Build your school.

A calm walking tracker for people who want to walk more, not chase numbers. Tap Start Walk, walk, and log it. Every walk becomes a dot in your mosaic. No daily step goal. No leaderboard. No account. No ads. Just one intentional walk at a time. HOW IT WORKS • Tap Start Walk. Time, steps and distance run quietly while you walk. • Hold to end. The walk is logged and today's dot fills in. • Add a note if you like ("felt better after this one"). • The home screen leads with "Walked 4 of your last 7 days". Consistency first; your streak is a quiet detail underneath. FREE • Unlimited walks with time, steps and distance • Your last 30 days as a mosaic, colored by morning, afternoon and evening • Share your mosaic as an image • Light and dark mode, metric or imperial • In 10 languages JUST WALK PRO (ONE-TIME PURCHASE, NO SUBSCRIPTION) • Your full history: every walk since day one. Free never deletes older walks; Pro shows them. • Month by month: a clean card for every month you walked • Color themes: warm, nature, mono or emoji dots • Lifetime stats: days walked, distance, steps, averages and your best streak APPLE WATCH • Start an outdoor walk on your wrist and leave your phone at home. Time, distance and heart rate are saved to Apple Health. (Watch walks don't appear in the phone mosaic yet.) PRIVATE BY DESIGN • No account, no social feed, no public profile • Location is used only during a walk to measure distance. It never leaves your device, and Just Walk collects no data. WHAT PEOPLE SAID "The mosaic idea is probably the strongest part. It gives a sense of progress without making the user feel judged." (a commenter on r/iosapps) I built Just Walk after losing about 60 pounds, mostly by walking. I wanted an app that counted the walk, not every step of my day. If something feels off, Settings → Send Feedback comes straight to me. Just Walk is not a medical device and does not give medical advice. Privacy Policy: https://dahvio.com/just-walk-privacy
