Be there for the whole ride.
Live GPS tracking for gravel, road, ultra, and audax — from the phone already in your jersey pocket. Share one link and everyone you love follows every mile, all day on one charge. Free for riders, forever.
Mass starts · Gun starts
The gun fires. The whole field goes live.
One start moment for everyone. The instant the gun fires, every rider's clock, position, and leaderboard entry starts together — no staggered app-fiddling on the start line.
Warm-up loops and rolling to the line don't count. Anything recorded before the gun is discarded, so top speeds and distances come from the race — not the car park.
Run your race on AsterIn the race
Built for the way cycling races.
Checkpoint racing
The gap right now, not at the last CP.
Checkpoints, splits, and live gaps for point-to-point and ultra formats. Watchers see who's moving and who's stopped for a resupply — as it happens, not hours later.
Built for the long stuff
The line stays on when the bars don't.
Gravel, audax, and multi-day ultras roll through dead zones. Pings queue on the phone and fill in the moment signal returns — the trail catches up and nothing goes missing.
No hardware
The tracker is already in your jersey pocket.
No satellite units to rent, charge, hand out, or chase back after the finish. The phone a rider already carries is the tracker.
Already trusted on gravel
