It's an app called Harry's Lap Timer, it does the data & video recording and the video overlay all within the app, it's amazing what this one app does. You'd have to spend a lot more to record the data, record video and then a lot more time on a computer to overlay the data on top of the video.
To get RPM and throttle position, you need a bluetooth obdII adapter. I have one called GoPoint BT1. Bluetooth adapter can also be used with other apps to read and clear codes.
