About

Mochi

Mochi is a watch-first wellness companion. Adopt a tiny virtual pet on your Apple Watch and care for it through your own everyday habits — walking, going to bed on time, taking little movement breaks. The kinder you are to yourself, the happier your buddy gets. A WATCH-FIRST EXPERIENCE Most pet apps live on your phone. This one lives on your wrist. Big buttons, one-handed reach, Digital Crown action selection, gentle haptics. Three swipeable pages let you check on your pet, take a quick action, or peek at today's progress in under 5 seconds. HABITS, NOT TAPS Your pet's mood, energy, and bond don't come from mindless tapping. They come from real-life activity — your daily steps, your sleep schedule, your movement throughout the day. Hit your gentle step goal and your buddy lights up. Go to bed near your bedtime and they wake up bright-eyed. SOFT, NOT STRESSFUL We never let your pet die or shame you. The toughest mood is "needs care", not "dying". Notifications are friendly nudges, never guilt trips. Three difficulty levels — start Gentle, grow into Balanced or Spirited if you want more feedback. QUIET PROGRESS 30–60 seconds a day is all it takes. Your phone quietly handles the heavy lifting in the background; the watch is where the relationship lives. WHAT'S INSIDE • Five adorable companions: kitten, puppy, bunny, dragon, panda • Watch home screen, action carousel, stats, and rewards • Five care actions: feed, play, walk, rest, clean • Apple Watch complications: circular, rectangular, inline, corner • iPhone Lock Screen and Home Screen widgets • Step goal with celebration at 25 / 50 / 75 / 100 % • Bedtime reminders that respect your schedule • 14-day stats and mood timeline on iPhone • Wardrobe with hats, scarves, backgrounds, and toys • Streaks and gentle daily rewards • Three difficulty levels — Gentle by default • Light and dark themes that follow your watch face PRIVACY FIRST Mochi reads steps, active energy, and sleep from Apple Health on your devices. Nothing leaves your iPhone or Apple Watch. There are no servers, no analytics, no ads, no third-party SDKs, no tracking. Ever. NOT A MEDICAL APP Mochi is a wellness companion for daily motivation. It is not a medical device and does not diagnose, treat, cure, or prevent any condition. Always follow the guidance of your healthcare provider. REQUIREMENTS • iPhone with iOS 17 or later • Apple Watch with watchOS 10 or later (recommended; the iPhone app works standalone too) • Apple Health access is optional — Mochi works in manual mode if you decline Built with care in Belgrade by Grigory Varlamov.
