About

Hearth Island

Features
Read 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.
