pomu turns your iPhone into a small, living companion. Not a habit tracker. Not a productivity app. Just a tiny pet that lives in the Dynamic Island, sleeps in StandBy, and quietly notices your tiny wins. — A SECOND, NOT A SCREEN — Bind pomu's shortcut to the Action Button. One press from your pocket = one tiny win. The Dynamic Island flashes a celebration. Your pet eats. That's it. — LIVES WHERE YOUR PHONE LIVES — • Dynamic Island Live Activity for instant pet reactions • Lock-screen widgets (rectangular, circular, inline) • System-Large widget that doubles as a StandBy bedroom • 21:00 nightly recap — never guilty, always gentle — SIX TINY FRIENDS — Sprout, Cat, Mushroom, Jelly, Ghost, and Pixel Dog. Their room evolves with your day — a lamp, a window of weather, a small plant. — ALIVE, NOT A STICKER — Your pet breathes, blinks, glances around and wears its mood on its face. Poke it and it squeaks, tickle it and it giggles, pet it in its room and hearts float up. Every tiny win makes it hop for joy. — ON iPAD, TOO — A big stage for your pet, a cozy room diorama, pointer hover and keyboard shortcuts (⌘L logs a tiny win). Home Screen and Lock Screen widgets keep it close. — GENTLE BY DESIGN — We deliberately do NOT have streak shaming, stamina, ads, or push pressure. The unit of progress is "tiny" — a sip of water, a breath out, looking up from the screen for ten seconds. — PRIVATE BY DESIGN — No account. No login. No analytics SDK. No tracking. Everything lives on your device. With pomu Pro your pet and tiny wins sync between iPhone and iPad through your private iCloud — we never see your data. — pomu PRO (one-time purchase, optional) — • Rare pets — Jelly, Ghost, Pixel Dog • StandBy bedrooms — rain, snow, sunset • Seasonal events — cherry blossoms, fall leaves • iCloud sync between iPhone and iPad • Mood-aware notes from your pet Pro is a single one-time purchase — no subscription, nothing renews. Restore it any time from the Pro screen. Privacy: https://blue-code.github.io/legal/pomu/privacy.html Terms: https://blue-code.github.io/legal/pomu/terms.html Support: sukhaverse@gmail.com
