For the ones waiting
“Somewhere past CP2” is not an answer.
When someone you love is hours deep into a race, the silence is the hard part. A text at the last checkpoint tells you where they were. The live map tells you where they are.
They're moving. They're okay. You can see it. The whole field, the gaps, the finishes — live in any browser, from one shared link. No app to install, no account to make.
How it works
Start. Share. Finish watched.
Tap Start. The phone already in your pocket becomes the tracker — no unit to rent, charge, or hand back.
Share one link. Anyone can open it in any browser and follow you live on the map. No app, no account, no login.
Finish watched. The moment you cross the line, everyone following knows — and the whole ride or run is saved.

The honest answers
The questions everyone asks. Answered.
Dead zones don't break it.
No signal on the moor or in the valley? The phone keeps recording offline and catches up the moment signal returns. The trail fills in and nothing is lost.
All-day tracking from one charge.
Tuned for endurance, not for burning the battery. Riders and runners track all day on the phone they started with.
Free for athletes. Forever.
Tracking, sharing, and being watched cost you nothing — not a trial, not a tier. Organisers pay for events; you never do.
Help knows where you are.
SOS sends your live position to your people. Hopefully you never tap it. If you do, it works.

Any distance · Any surface
Every mile deserves a witness.
A gravel race through the dust. A dawn start on a 100-mile trail ultra. The club run that got carried away. If it's worth doing, someone wants to watch you do it.
Start tracking — free

The good bits
Nobody frames a results PDF.
The finish-line hug. The mate who rode the last 40 km on your wheel. The dog that met you at mile 20. Sport is better when the people who care get to be part of it — and now they can be, from anywhere.
Track it. Share it. Let them cheer at the kitchen table.
Start tracking — freeThe Aster community
Every dot on the map is somebody's whole race.
Finish lines, club runs, first ultras, last-minute sprints for the village sign — all of it live, all of it shared, all of it watched by the people who care.
