TRACE
Your 0–60, timed.
Your run, on film.
TRACE turns the phone already in your pocket into a performance recorder: standing and rolling times, the quarter mile, laps, top speed, G — and video with the numbers burned into the picture. Nothing leaves your phone.
Every number a strip or a stopwatch would give you
- Standing starts
- 0–30, 0–60, 0–100 mph; 60 ft, ⅛ and ¼ mile. With or without the 1 ft rollout drag strips use, switchable, and every stored result re-times when you flip it.
- Rolling windows
- 20–60, 40–80, 60–100 and any window you define. Rolling ⅛ and ¼ too.
- Laps
- Gates you place on the map. A track-day mode that expects them.
- Peaks
- Top speed, peak acceleration and braking G, climb and descent from the barometer.
- Confidence
- Every result is rated GOOD to POOR by the data behind it — how clean the GPS was through the run — never by how you rode.
Measured, not estimated
Phone GPS updates once a second. TRACE is built around that limit instead of pretending it isn't there, and every number it publishes is checked against a RaceBox Micro — an independent 25 Hz racing GPS — before it ships.
A launch that eases away has no single instant to measure from, so a fumbled start reads roughly twice as far off. That is why a GPS-projected launch shows one decimal and one the accelerometer located shows two: the display never claims more precision than the measurement has.
Record the ride. Keep the run.
The numbers on the picture
Speed, ride clock, distance and heading over the frame, and the run in flight on its own card — with a line that fills as the quarter mile goes by.
A run is already trimmed
Open a run from its time and the clip is cut to it, three seconds either side. Drag the ends, hold to zoom, export with the mark, share it or save it to your phone.
The highlight reel
An opening card with the date and the numbers, every run whole and one after another, a mini map in the corner. Pick which runs; it plays them in the order they happened.
Built for a hot phone
A minute of viewfinder to aim, then the screen goes dark to save heat. Sound from the phone, a USB receiver or a Bluetooth lapel mic. Heat or the lock screen ends a clip — never the ride.
Every vehicle, every ride, every best
Vehicles
Photos, an odometer that keeps itself, service intervals, and one-off "inspect this" items with a mileage attached.
Personal bests and trends
Best per metric per vehicle, and how each has moved over the season.
Segments and ghosts
Save a stretch of road and compare every run of it. Import a friend's ride export and race their ghost over the same segment.
Playback
Every ride replays on the map with the speed trace; play from any spot, at any rate.
Nothing leaves your phone
No account. No server. Rides, video and sensor data stay on the device, and sharing is a file you hand over yourself. The map loads its tiles from OpenStreetMap, as any map does; that is the only network request the app makes. The whole policy is one page.
