TrackChronos / Motorsport telemetry system

TrackChronos

Every track day you've filmed is data you never got to use.

TrackChronos turns that GoPro footage into lap-by-lap telemetry: speed, lean, braking and your line, side by side with the video.

Built by a rider,
for riders.

I was riding on track, recording every session with my GoPro, when I realised I'd accumulated hundreds of gigabytes of footage sitting on drives going nowhere — track days I couldn't learn from because the data was locked inside a camera. So I built the tool I actually wanted.

— James Alexandre, creator
Philosophy
Local First Your sessions are yours. TrackChronos runs on your machine, so your footage and telemetry stay there.
Purpose-built Built for reviewing track days, not generic dashboards. Every screen is there to help you find time.
Simple Pricing Track days cost enough already. Pay once, use it forever. No subscription.
Where It's Headed

GoPro was the starting point, not the ceiling. SpeedAngle data is already supported, and the goal is to bring in as many telemetry sources as make sense — so that wherever your data comes from, TrackChronos can make it useful.

The ambition is straightforward: every rider who turns up at a track day should have access to the kind of analysis that helps them improve. Not just the ones with factory budgets.
