Your daily health goals, growing into a living world. Tiny Habits is an Apple Health tracker that turns your steps, water, sleep, daylight and mindfulness into a realistic 3D planet. Reach your goals and watch mountains rise, rivers fill, forests mature and meadows bloom. Completely rebuilt for version 2.0, the new Living World replaces the original low-poly planets with detailed terrain, seas, forests, clouds and weather. Explore a world shaped by the days you actually live. YOUR HEALTH DATA BRINGS IT TO LIFE Connect Apple Health, choose your metrics and set your daily goals. Tiny Habits uses the data you already record to grow your planet automatically, without another checklist to maintain. Five habits shape five parts of your world: • Steps raise mountains. • Water fills seas, lakes and rivers. • Daylight grows forests. • Sleep brings meadows and flowers. • Mindfulness clears the skies and lights the aurora. SMALL STEPS. LASTING GROWTH. Every day is another chance to grow. Miss a goal and that part of your world waits; the growth you have already earned stays. Pick up again tomorrow. When you grow matters, too. Forests planted early have time to mature, while later growth appears young. Your world tells the story of your month. EXPLORE WHAT YOU HAVE GROWN Fly from space down into your planet's forests and valleys. See your daily progress in the landscape, then replay how your world has changed. BUILD STREAKS. UNLOCK DISCOVERIES. Reach your goals consistently to reveal wildlife and landmarks: grazing herds, whales, waterfalls, stone arches, old-growth groves, the aurora and more. Collect discoveries as they appear in your world. A FRESH WORLD EVERY MONTH Start a new planet on the 1st. At the end of the month, it joins Your Year, preserving the world your habits created. Look back through your months and see your progress as places you can revisit. With any Planet Pack, your monthly worlds become a solar system orbiting a sun shaped by your year. TWELVE LIVING WORLDS TO DISCOVER Begin with Terra, the free Earth-inspired world. Planet Pack 1 adds eleven more Living Worlds, from frozen lakes and desert oases to jungle islands, volcanic landscapes, cherry blossom valleys and glowing forests. Explore the world gallery, watch each planet grow and preview your own month in different worlds. GOALS THAT FIT YOUR LIFE • Choose the Apple Health metrics that shape your world. • Swap a default metric for walking and running distance, cycling, swimming, active calories, exercise minutes, stand hours, flights climbed or workouts. • Set a personal daily target for each metric. • Schedule weekly and month-end reminders. • See your progress with Home Screen and Lock Screen widgets. • Use VoiceOver and Dynamic Type. YOUR HEALTH DATA STAYS WITH YOU Your health data is read from Apple Health, used to grow your world and stored on your device. It is never uploaded. You choose which Health permissions to allow and can change them at any time. Already using Tiny Habits? Your past months are regrown as Living Worlds in Your Year. Existing Planet Pack 1 owners receive its eleven additional Living Worlds and the solar-system view. Shape your world, one tiny habit at a time.

Download and instantly look back at roughly the last 7 days of sleep — no waiting, your sleep report is right there when you open the app. Beyond automatic tracking, you can add entries on the timeline, drag to adjust them, and tag them as Reading, Exercise, or Entertainment. The app automatically tracks your sleep at night: when you fall asleep, when you wake up, and how long you slept — all recorded on the timeline. Sleep ratings are based on your sleep duration between 9 PM and 9 AM the next morning — Lion, Dog, Boar, Owl make your sleep quality clear at a glance. No manual steps needed — just put your phone down and sleep. It works without an Apple Watch, and gets more accurate with one. Key features: • Sleep tracking: automatic records of bedtime, wake time, and duration • Timeline entries: long-press to add a record, drag either end to fine-tune the time; tag it as Reading, Exercise, or Entertainment • Animal ratings: four animals show your sleep at a glance • Calendar review: see every day and every segment at a glance • Home screen widgets: Sleep Clock, Monthly View, Lion Box, Recent 7 Days, Sleep Brief, and more • Monthly statistics: review the whole month and find your personal "sleep sweet spot" • Sleep sounds: built-in playlists — tap the vinyl and it plays, with sleep timer, lock screen, and AirPlay controls Your sleep data stays on your device and syncs between your devices through iCloud (encrypted by Apple). We never touch your personal data. —— AnimalSleep © water Acknowledgments:

Verdict

The call

The clearest difference is update cadence: AnimalSleep at every 2 days against Tiny Habits's monthly. AnimalSleep also leads on ratings volume (5 vs 1) and iOS requirement (16.0 vs 26.0). Tiny Habits's advantage is rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.
