The #1 accessory you can get to go faster on the track!!

I kid you not- as a weekend track addict (I try and do about 6-8 weekends a year) I find Harrys Lap Timer to be the best investment I have made that has made me improve my times! Being able to capture consistent data points, sector/lap times and being able to overlay video (with MultiCam support of GoPro!) allows one to see where they are doing well and where one can improve.

My favorite things about the app:
* support for OBDII sensors
* support for external GPS
* support for multi cameras (iPhone, iPad and GoPro cameras)
* in-device support for overlaying multiple videos, data points from sensors on to track map
* ability to set a Reference lap and compare all other laps to it

Only a fellow track addict can develop such an app - and it shows how well its been written!
