About
Build better habits with friends by building a city together.
Found a city with up to 7 friends and agree on a daily goal — run a mile, read 20 pages, no sugar, anything. Every day everyone marks it done, construction advances: houses in a day, apartments in three, skyscrapers in a week — all rising in a hand-crafted 3D city that represents your consistency.
The catch: the city only grows when the whole crew delivers. Miss your goal and your building collapses. Miss a week and an asteroid destroys part of your city. Keep yourself and your friends accountable.
Forgiveness built in: Streak freezes bank automatically as you build, covering the occasional bad day — and a recently broken streak can be repaired with one tap. Life happens; abandonment costs.
• Real accounts — your cities follow you to any device
• Invite friends with a 6-letter code
• Live progress: see who's built today and who's holding out
• Streaks, freezes, milestones, and a city that remembers everything
Found your city. Pick your goal. Don't be the reason your city doesn't grow.
