Do I press on the little blank box with my finger? Doesn't seem to work? Sorry if I'm just being dense?
For Autocross, you may consider just leaving the start coordinate blank, which will cause it to auto-start upon movement from a stop. If your event's timing starts at a point after the vehicle's actual start, then that's when you might want to set a specific start coordinate. Timers are 10 - 20 ft from start.
You can optionally set the finish point to make the timing automatically stop at that point, and then the overall session will stop about 15 seconds after. Obviously, a smartphone's GPS accuracy will not perfectly match the high-precision laser timing system used in most autocross events, so the run times calculated here are an approximation that will depend on the quality of the GPS data and start/finish coordinates. The main objective is that it records the data and video to cover the time span of your session, which it does very well.

If you don't opt to set the finish point, then the session just ends whenever you press one of the navigation tab buttons other than "Record".
