Best track app!

I reviewed other versions of this app in the past, and this review is going to be more of the same praise. Harrys GPS Lap Timer provides as comprehensive a solution as the iphone can handle, performing much of the same functionality as the vastly more expensive dedicated timing solutions, requires virtually no setup at the track, and just flat works!
Used the Petrolhead version at Indy Motor Speedway this past weekend (my 7th event this summer), and impressed my garage-mates with the timing and video the app produced.
Additionally, I had a question over the weekend that I posed to Harry; he responded very quickly, and I was up and running for the next session. Brilliant app and fantastic customer service!
