A territory-running game

Close the loop.
Claim the land.

Run back to where you started to claim the area inside your route. Other runners can take it from you, and it gradually fades if you don't run it again.

Your territory follows the loop you run, whether it's around a park or your neighbourhood.

How it works

How to claim your first area

Pick a route that brings you back to the start. Then see who comes to challenge your claim.

Run a loop

Record your GPS route and return within 35 m of the start to close the loop.

Claim real territory

Claim the area inside your route. If it overlaps another runner's territory, only the overlapping part changes hands.

Territory fades in 7 days

If you do not run it again, your territory fades. The app warns you before it does.

Take over & reclaim

Others can run over your territory to take it. Reclaim within 48 hours for 2× season points.

Running & stats

Look back at your runs

See when you ran, how fast each kilometre was, and which areas you claimed.

Three running modes

Run to claim territory, head out for a free run, or follow a workout from your plan.

Your runs on a calendar

Green marks a territory claim, gray marks a run without one, and a heart marks a run synced from Apple Health. Streaks count by week.

Pace, splits and routes

Check your time for each kilometre, follow your pace on the graph, and see your route and claimed area on the map.

Personal stats and heart rate

See personal stats, plus heart rate and calories when your Apple Health runs include data from a watch or chest strap.

Community & seasons

Bring your running friends

Follow your friends' runs, join a club, or compete for points each month.

Seasons & rankings

Earn points to move up the tiers each month. Check the overall standings or compare with nearby runners, friends and clubs.

Feed & clubs

Catch up on runs from people you follow. Start a club or join one, then check the club standings.

Challenges & events

Enter challenges on your own or as a team, with separate standings for each challenge. Sign up for running events and get a reminder before they start.

Fair play

Every run gets checked

ZAYN calculates distance and pace from your GPS route and checks for sudden location jumps or unusually high speeds. Runs synced from a watch go through the same checks.

FAQ

Before your first run

How far do I need to run to claim territory?

There is no set distance in kilometres. Run back to within 35 m of your start. ZAYN calculates the area inside the loop and removes fragments smaller than 200 m².

Can other runners take my territory?

Yes, but only the overlap changes hands. Within 30 minutes, a challenger needs both a faster pace and a larger area.

What if I do not run it again?

Territory fades over seven days, but is never deleted. Run it again to keep it alive.

Is Android available yet?

Not yet. You can try the iPhone beta through the TestFlight link above.
