Your focus is the only thing that grows here. Start a timer, put the phone down, and do your real work. Every finished session brings a small, dying island back to life. HOW IT WORKS TerraFocus wraps a focus timer around a barren island. When the timer runs out you earn biomass, and biomass is the only way to buy the machines that heal this place. TERRAFORM, STEP BY STEP Nothing is painted green by hand. You build infrastructure, and the land reacts: • Wind turbines and solar panels lay down power • Air purifiers unlock scorched ground • Excavators and trenchers dig the canals • A water pump fills them, and the water spreads on its own • Irrigators carry moisture inland Barren rock becomes sand, then soil, then grassland, then wetland. The island only ever moves forward. Nothing you heal can be lost. TWELVE MACHINES, ONE CHAIN Each machine has a job and a range, and the order matters: no water without power, no wetland without a canal nearby. Working out the sequence is the game. 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. PICK YOUR RHYTHM Choose 5, 15, 25, 45 or 60 minutes. Every duration pays the same rate, so you choose your rhythm, not your exploit. 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; an optional account syncs your island between devices Terraforming meets deep work. Do the session, keep the island.
