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. Learn more →
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. Learn more →
Head-to-Head + AI feedback
Compare up to four drivers corner by corner to see exactly where you gain or lose time — then get free AI feedback on what to change. The AI runs on our own server, not a cloud service. Learn more →
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.
…and a lot more under the hood
All free — no subscription, no hardware.
Works at any track
Upload data from any circuit — the GPS map and corner detection adapt automatically.
Built around AiM data
Track Day Analysis specializes in AiM. Upload your data from a Solo 2 or other AiM device — raw XRK or an RS3 CSV export — and it just works, with every channel detected automatically.
Don't have a logger yet? The AiM Solo 2 DL is a great place to start — GPS lap timing plus the data that makes this kind of analysis possible.
Already on MoTeC, RaceChrono, VBOX, or Garmin? Those work too.

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.
