Harry's LapTimer Rookie-apprecensioner

Accurate laptimer with extensive data collection. I use it on my motorbike on track and it is very easy to use, just walk up to/near start/finish line and set poi, then push go when ready, twist throttel on green light. The laptimer will do everything from there on without any interaction. Afterwards you can analyse data on iPhone. With speed diagram you can see Breaking points, gear changes, curve speeds and more. The lap export function is very nice and important. Developer replies on question

I really do like this app. It has all the functions I need for a Laptimer and even more. Video with overlay is simple to use. It keeps up with development of other devices like external GPS and OBD. Summary! A perfect app that a newbie like I was can use and more experinced user.

Had the Rookie version but upgraded to Petrolhead asap. So easy to follow your improvements lap by lap. The one thing I miss is a nice export format for all the lap times. Preferably session by session, lap by lap in a nice graph. But I still recommend this app! Cheers Ronny

I need instructions! I'm sure this is a good app, if I find out how to use it.
