Every session,
at a glance.
Sector splits, track map, theoretical best — the moment a session loads, GTelemetry lays out exactly what happened, lap by lap. No digging through raw data to find the story.
Ride along with yourself. Rebuilt or real.
No camera? GTelemetry rebuilds a full driver's view from telemetry alone: real corner names, trackside scenery, two laps side by side, any circuit, any time of day. Got onboard footage? Load it, set one sync point, and the video follows your lap as you scrub. Your video never leaves your computer.
See exactly
where it happens.
Every analysis card doubles as a track map — coasting, braking, traction, all of it recoloured onto the racing line with real corner names, fastest lap next to pinned, side by side. The same events also line up in an Analysis Lane on the timeline below your laps, beside a live lap-delta trace, so you can hover any moment and jump straight to that exact point on track.
Thirteen coaches.
Zero guesswork.
Braking zones, throttle application, traction circle utilization, driving line — thirteen focused diagnostics compare your pinned lap against your fastest, and tell you exactly where time is won or lost.
Don't just read it.
Watch it.
Every coaching card plays the technique it's asking for, on the real corner from your lap. The car, the line, the pedals, the wheel and the G-dot all move together, and a second car shows the common mistake falling behind. It knows what comes next, too: before a long straight it trades a little entry speed for a better exit.
The coach's notes,
built in.
Every card links to a long-form guide on the skill behind it: what it is, why it costs you time, and drills to fix it. Guides open beside your session, so you never lose your place, and the parts that don't apply to your car or surface fade back.
- 13 card guides, one for every coaching card
- 6 Foundations: grip and weight transfer, corners and elevation, vision, surfaces and tyres, setup by class, racecraft and penalties
- Fundamentals to Advanced, for the sim and for track days
Or just read
the whole lap.
Every card's findings melded into one plain-English walkthrough — corner by corner from the start line, exactly where you gained and lost time, and what to try next.
Not Just Sim Laps.
Import a RaceBox GPS lap-timer session from a real track day and get the same driver's-view render, the same lap comparison, the same coaching — built from GPS alone, in the same Library as your sim laps. Find out more →
One Library.
Sim and real, together.
Every session you save lands in one Library, grouped by track, so your Gran Turismo practice sits next to your real track days. Learn a circuit in the sim, then check which habits came with you.
- Compare across sessions: pick laps from different days and save them as one comparison
- Theoretical best stitched from your best sectors
Beat your mates,
lap by lap.
Send a friend your session and they can lay their lap over yours, corner by corner. Then tell them where they lost it.
- Private by design: there's no public directory, so people can only find you by your exact @username
- Read-only shares: a friend gets a copy to study, which they can't download or pass on
- Messages built in, with blocking and reporting
Three steps to your first debrief.
