Your pet is only alive because you focused. Mochiverse is a focus timer with a pixel creature living inside it. Start a session, put the phone down, and your Mochi grows. Neglect it, and it doesn't. HOW IT WORKS - Hatch an egg. One of 5 species, chosen at random. - Pick 15, 25, 45 or 60 minutes, or set your own. - Focus. Your Mochi sleeps beside you and gains XP the whole time. - Finish and earn coins, food and a streak day. - Feed it, play with it, keep its health up between sessions. IT CAN ACTUALLY DIE Hunger, mood and health drain in real time, even while the app is closed. Let health hit zero and your Mochi is gone for good, into the Memorial Garden. It turns out nothing makes you come back tomorrow like a creature that needs you. 31 FORMS TO DISCOVER Every Mochi evolves through a branching tree, and the branch it takes depends on how you actually cared for it. Feed it well and it grows one way. Play with it and it grows another. Your Collection remembers every form you have ever reached. BUILT FOR REAL FOCUS - Live Activity on the Lock Screen and Dynamic Island. Check the timer without unlocking. - Home Screen widget with your pet, your streak and today's minutes. - Focus subjects. Tag sessions as Math, Work, Reading, whatever you like. - A daily reminder at a time you choose. - Ambient sound while you work: lofi, piano or rain. - Streaks, session history and per-subject stats. MOCHIVERSE PREMIUM - Free revives. Never lose a pet for good. - Pets decay 40% slower, so they need less babysitting. - 11 extra themes: sunset, aurora, sakura, midnight, galaxy and more. - 7 exclusive pet skins: golden, cosmic, mint glow and others. - Pro stats: weekly goals, deep charts and per-subject reports. Available in 10 languages. No account required. No ads. Mochiverse Premium is a monthly auto-renewing subscription. Cancel anytime in Settings.

Hearth Island
Read full descriptionHide full description
Start a focus session. When you finish, a tiny 3D island grows - and it keeps living while you're away. FOCUS. EARN. GROW A LIVING WORLD. Hearth Island turns the minutes you focus into something you can see. Set a timer, put the phone down, and do your work. Every focused minute earns one Spark. Spend them to plant trees, build cottages, adopt a companion, and raise whole new islands out of the sea. Nothing here is bought with money. Sparks are earned only by focusing - that is the whole point. A WORLD THAT LIVES ON ITS OWN - Real day and night, drifting clouds, and rain that ripples the sea - Four seasons that follow your real calendar - spring blossom, summer fireflies, autumn leaves that fall and gather, winter snow on every roof - Mochi, a companion who wanders the island, plays with a yarn ball, and naps in a little bed - Plants that grow a stage with every session you complete THE FOCUS THAT EARNS IT - Simple sessions - pick a length, start, and focus - Leave the app mid-session and it gently pauses instead of punishing you; a screen wake-lock keeps the phone awake while you work - Optional Focus Shield quiets notifications for the length of a session - Early ends still bank the minutes you focused - you are never punished for stopping GROW THE ISLAND - Plant flowers, bushes, pines, oaks and maples - Build cottages, cabins, a greenhouse, a lighthouse and a dock - Raise new land - Sunny Meadow, Quiet Cove, North Ridge - from open sea - The flagship moment: build the Bridge and a brand-new isle rises, "New area discovered!", with more ground to make your own FREE, AND ACTUALLY GENEROUS The whole loop - focus, earn, plant, build, grow - is free. You can fill a whole island without paying a cent. HEARTH PREMIUM Premium opens the full catalog - palms, campfires, wishing wells, cabins, greenhouses, lighthouses, companion pieces, and new islands as they arrive. Premium items still cost the Sparks you earn by focusing; money only opens the catalog, it never buys progress. $4.99/month, $29.99/year with a 7-day free trial, or $59.99 once for lifetime. Everything lives on your device. No account, no sign-up, and your island is never uploaded anywhere. Requires iOS 15 or later; the living 3D world needs a device with WebGL2 (iPhone 8 and later). ---------- Hearth Premium is available as a monthly ($4.99) or yearly ($29.99, with a 7-day free trial) auto-renewable subscription, or a one-time Lifetime purchase ($59.99). Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings.
