Testing Harry's LapTimer in a Jeep Wrangler Unlimited Rubicon on a snowy winter's day in the Fraser Valley, heading up towards the Winter Park Ski Resort.

I use an iPhone 5S to run Harry's LapTimer and for the main video recording. A GoPro Hero3+ was attached to the rear driver's side door for the picture-in-picture video view. A GoPoint BT1 ODB-II to Bluetooth dongle provided the diagnostic data to the app, and a Dual XPS150 provided the high-precision GPS input.

Harry's LapTimer users the gear ratios and tire size data to determine which gear your manual transmission is in, and I believe I had some typos in that, so the 4th to 5th gear changes weren't registering properly.
