Live telemetry & predictive timing
Lap time, delta to your best, predicted lap and speed — live on your phone, big enough to read at 120 mph.
Track-day telemetry, forged simple
LapSmith turns your phone into a race engineer. Live timing on track, corner-by-corner audio coaching against your own best lap, and broadcast-style video overlays — synced automatically from GPS, engine and camera data.

Lap time, delta to your best, predicted lap and speed — live on your phone, big enough to read at 120 mph.
Scrub through every lap, overlay speed and braking traces against your best, and see exactly where the time went.
LapSmith matches your GoPro footage to GPS and engine data automatically, then exports broadcast-style overlay videos ready to share.
A voice in your helmet that knows your best lap. Brake later, turn in earlier, carry more speed — cued before the corner, not after.
RaceBox GPS, OBD engine data, GoPro and heart-rate sensors connect side by side — with clear status for every device before you roll out.
Lap time, delta and session status on your car's own screen — phone mounted or pocketed, eyes where they belong.
Race procedure
Pair your RaceBox, OBD adapter and GoPro once. LapSmith remembers your rig and checks it's ready before every session.
Laps detect automatically at the start-finish line. Live timing on screen, coaching in your ears, everything recorded.
Compare laps corner by corner, find the time, and export overlay videos that look like they came off a race broadcast.
In the pit lane
Screenshots are placeholders for now — real captures drop straight into these frames.
On the dash
With CarPlay, LapSmith puts lap time, predicted lap, delta and data quality on your car's built-in display. No suction mounts, no glancing down — just the numbers that matter, at a glance.
