Pace Notes

AI-generated
co-driver calls.

After recording, RallyTrax analyses your track's geometry — every bend radius, elevation change, and straight — to generate authentic rally-style pace notes, graded 1 to 6 just like the pros use.

"Left 3, tightens"
Medium bend, radius decreasing
"Right 4, over crest, 120"
Firm corner with elevation, 120m to next
"Hairpin right"
Grade 6 — extreme, 150°+ deflection

Replay

Your co-driver
rides shotgun.

Select any saved track and hit replay. As you drive, RallyTrax matches your GPS position to the route and reads out pace notes through your speakers — timed to your speed, with a chime before each call.

How It Works

Three steps to your
personal rally stage.

1

Record your drive

Tap the record button and drive your favourite road. The app captures GPS coordinates, speed, and elevation every second.

2

Notes are generated

RallyTrax analyses the track geometry and produces rally-style pace notes — turns, crests, straights — graded on the 1-to-6 severity scale.

3

Replay with co-driver

Drive the route again while your phone calls out every turn ahead of time — timed to your speed, just like a real rally co-driver.
