About

TerraFocus

Features
Read full description

Your focus is the only thing that grows here. TerraFocus wraps a focus timer around a small, dying island. Start a session, put the phone down, and do your actual work. When the timer runs out you earn biomass — and biomass is the only way to buy the machines that bring this place back to life. TERRAFORM, STEP BY STEP Nothing is painted green by hand. You build infrastructure, and the land reacts: • Wind turbines, solar panels and dams lay down power, pylons carry it • Toxin scrubbers turn polluted wasteland back into soil • Trenchers and excavators dig the canals, a water pump fills them • Irrigators turn soil into grassland, and water makes wetland • Beehives bring flowers, a controlled burn and an arboretum grow a forest When the island is alive, you take every machine down and give it back to nature — then sail to the next one. A WORLD THAT KEEPS LIVING Day turns to night on its own. Street lamps switch on, machine LEDs glow, moths gather around the light. Trees grow, age, lean over and are replaced by other species. Squirrels move into the woods by day; frogs appear at the water's edge by night. None of it is a score. It is simply what a healed place looks like. HAND-MADE ISLANDS, REAL PUZZLES Six small training islands introduce the machines two by two. Then every island is a hand-drawn puzzle with a tight budget: where does the only rock sit, which way should the L-shaped irrigator face, which meadow do you burn? The fewer leaves you spend, the more stars you earn. TWENTY MACHINES, ONE CHAIN Each machine has a job and a shape, and the order matters: no water without power, no forest without ash. Working out the sequence is the game. BUILT TO BE HONEST • The timer measures real time — it keeps running while your phone is in your pocket, and finishes on its own • No ads • No streak to punish you for a bad week • Plays fully offline — no account, no sign-in, no data leaves your device Pick 5, 15, 25, 45 or 60 minutes. Every duration pays the same rate, so you choose your rhythm — not your exploit. Terraforming meets deep work. Do the session, keep the island.
