It's was all gas, not brakes.
When just a little too wide......

I’m the developer of G86 Racing, from CrowFoundry. I wanted to show the part that may be useful for autocross: recording individual point-to-point runs and reviewing where the speed and elapsed time differ along the course.

The run-review workflow

1. Prepare the course as a point-to-point layout with separate start and finish lines, or record a learning run and save the full GPS path or a selected section as a reusable track. Check that the saved route and timing lines match the actual course before recording timed runs.

2. Record each run on your iPhone or Android phone. Local timing, the recorded path and session history are available without an account. You can return to the session and start the next run rather than treating everything as one continuous circuit lap.

3. With Pro, choose a reference and compare up to four runs over distance. Look at the speed trace and time gap through a section instead of only the finishing time. Shared point-to-point sections can be compared independently when the recorded paths overlap; the comparison does not invent times for undriven sections.

4. If you recorded onboard video, review it with the run. Pro can export a copy with a telemetry overlay, or export data as CSV, MoTeC i2 CSV, AiM CSV, VBO or JSON for another analysis workflow.

Phone GPS recording and local timing can work offline. Cloud sync and a remote live pit wall need internet. Engine data needs an actual supported source; a phone-only recording does not supply measured throttle or brake channels.

Free / paid

Basic timing and local history are free without an account. A free account adds the track editor, three onboard videos and one Pro demonstration session. Run comparisons, advanced analysis, overlays/exports and external telemetry require Pro. US App Store pricing is $14.99/month or $149.99/year, auto-renewing; current regional/platform prices are shown before purchase.

The attached interface examples use demonstration data, including a circuit comparison. They explain the controls and do not claim a measured autocross accuracy result.
