Clutch: Lap Timer & Pace Notes

Clutch writes your pace notes for you.

Record the road you drive, or import a route - Clutch works out every corner from the geometry, including which way it goes and how tight it is, then speaks them to you ahead of time while it times your laps from actual gate crossings.

BUILT AROUND ONE LOOP
- Tracks: draw the road you drive, or import a KML / GPX file
- Drive: arm at the start gate, and let the voice call the corners
- Review: see exactly what happened at every corner

CORNERS ARE GENERATED FOR YOU
You never type a pace note. Give Clutch a route - recorded by driving it once, or imported as KML / GPX - and it works out on its own:
- where the corners are
- which way each one goes
- how tight each one is
- how far it is from the next
Then it reads them back to you in order, ahead of time, as you drive.

FREE, PERMANENTLY
- Free Roam timing on any road, anywhere - no track needed, never limited, never counted
- Draw a track by hand, or import KML / GPX from Files, Mail, iCloud Drive or any share sheet
- Corner analysis and full-route preview: every corner, its direction and severity, on the map and in a list
- Play a single callout, or rehearse the whole route before you drive
- G meter with 1.5 / 3 / 5 / 8 G ranges and reference rings, altitude and heading, and a live microphone sound-level meter

TIMING THAT STARTS ON THE LINE
Timing begins on a measured start-gate crossing - not on a button press - so your lap time reflects the lap, not your thumb. Laps, best lap, segment (point-to-point) timing, and a result screen that shows corner speeds straight away.

REVIEW EVERY CORNER
Speed and G at each corner, a speed chart, a G chart, a colour-coded trace on the map, and a replay you can scrub through. Compare a wet run against a dry one on the same track, and see what the conditions actually cost.

PERFORMANCE TESTS
Measure acceleration runs and braking distance - a straight, repeatable measuring stick for the car itself.
