Upload your lap data. Visualize it in your browser for free right now.
Bring your data from almost any logger, build the panels you want, sync it to your video, share your sessions, and see how your laps stack up against other drivers — all in one place.
Free to use • You choose what to share • Built by a track driver, for track drivers
Free and instant — nothing to install. Sign up (also free) to save your sessions permanently, sync video with data overlays, share with friends or groups, and compare your laps on the leaderboard.
Your data, the way you want to see it
A fast, browser-based way to explore your telemetry.
Import from almost any logger
Upload AiM XRK, MoTeC, RaceChrono, VBO, and Garmin CSV files. Channels are detected automatically — bring whatever your system records.
Visualize in your browser
Everything runs online — open your session on any computer and start exploring your laps in seconds. Works on mobile devices too, including the iPad.
Fully configurable panels
Arrange the views you care about: GPS map, speed, friction circle, time delta, and every channel logged in your data — laid out the way you like.
Share on your terms
Share only the sessions you choose — privately with friends, with groups you create, or publicly with everyone. You stay in control of what's visible.
Leaderboard & comparison
See how your laps stack up against other drivers, then compare directly to find where the time difference is.
Video sync & overlays
Automatically synchronize your video to your data and add overlays driven by your logged channels — speed, RPM, G, and more. Export a clip of your best lap to download and share.
Comment & discuss
Leave comments on shared data — and pin them to specific parts of a session, like a particular corner or a point on any trace view.
Layouts that just work
Start fast with easy, pre-defined layouts, then customize everything to build exactly the workspace you want.
Works at any track
Upload data from any circuit — the GPS map and corner detection adapt automatically.
About Track Day Analysis
Track Day Analysis was built by an experienced HPDE driver and SCCA chief instructor.
Take the data you already log — whatever your system records — and make it easy to visualize in the browser, sync to your video, share with the people you want, and compare against other drivers.
It's free to use, and it's actively being developed. If you drive HPDE and want a better way to work with your data, give it a try.
