Checkin turns your favorite fitness activities into territory. Move more → Own more → Defend your city.
1) Convert your activity into territory
Steps, runs, rides, lifting sessions, and Strava syncs all fuel your territory.
2) Claim and defend your turf
Expand your hex-based territory and hold your ground against real people around you.
3) Compete with your city
See who dominates your neighborhood, your gym, or your entire region.
4) Power up with one tap
Your checkin button converts movement into instant tile growth.
Check-In is not another fitness app.
It’s the world’s first global territory game powered by movement built by and for people who love to walk, lift, bike, run, and compete.
