Bitty City: Habit Builder

New: your city builds itself. Every check-in goes straight onto what's going up next, and each one gets a celebration. Plus one streak across all your cities.

Build better habits with friends by building a city together.

Found a city with up to 7 friends and pick a daily goal: run a mile, read 20 pages, no sugar, anything. Every check-in builds your city. It goes straight onto what's going up next, and when your whole crew checks in, you earn a bonus. Watch houses, apartments and skyscrapers rise in a hand-crafted 3D city that grows with your consistency.

The catch: go a week without anyone checking in, and a meteor flattens part of your city. Keep yourself and your friends accountable.

Your streak is yours. One streak across all your cities, and any goal counts. Miss a day and a streak freeze steps in automatically.

• Share an invite link and friends land right on your city • See who's checked in today, and cheer them on • Add a photo as proof, or let Apple Health check you in • A celebration for every check-in: your streak, your buildings, your bricks • My Alive City (beta): a city just for you, built from your own goals

Found your city. Pick your goal. Check in and watch it grow.
