How it works
The only opponent is the city. Walk every street.
Start a walk
Tap Chart and go. City Charter uses your phone's location to see which streets you're on. It works with the screen locked, so your phone can stay in your pocket.
Watch the city fill in
Every street starts as a faint line. As you walk, each block lights up bright white and stays that way. Your map only ever grows.
Find what's left
Switch to Uncharted and only the streets you haven't walked yet are highlighted. When just a few small streets remain, they're easy to find.
Keep your Logbook
See every walk, your longest, your streaks, how much of the city you've covered, and which streets you're closest to finishing.
Your walks stay on your phone
There are no accounts to create. Your location is matched to streets on your phone and your progress is stored there too. Read the privacy policy for the details.
