Have an Iphone? Neat App to take track day video & data log!

[Chad-1stGen]

I've checked in on Steve Rupp's video from RTTC where Nathan is driving a BFG VIP a couple of times. I really like the info from Steve's racepak. Got me wanting to spend $$$ on another thing I don't need but really WANT.

So today I'm playing around with my IPhone and a lightbulb goes off. The Iphone has GPS and accelerometers maybe someone has an app to record some data. Doing some basic searches on my phone in the app store showed fairly poor results.

However, when searching on google I came across an app mentioned in a few places. Harry's Laptimer. I'm still reading up on it but thought I'd ask if anyone here has used it and let others like me who haven't learn about it.

This thing will take video of every other lap and record data for every lap. It needs the off laps to process the video. You can even make a video on your phone with a track overlay with speeds.

EDIT: Figured I'd throw on of the videos I actually recorded on the first post for those folks reading the first time. I have a lot more discussion later in the post about the app.



Here are two samples I found on youtube.

Porsche guy in Canada


EDIT: couldn't get the subaru vid to work so I found one from Buttonwillow (track semi-local to me)


You can download the data and slice and dice it off you phone too.

App only costs $6 right now for the regular version and $15 for the pro version on the app store. Though most people use a $100 tomtom cradle to attach the phone to the window for capturing video as well as use of the remote GPS sensor on the tomtom cradle for improved GPS accuracy. Some guys using the cradle are claiming lap time accuracy within 100th of a second of their transponders.

This thing is not substitute for a Racepak but if you already own the Iphone it sure looks awesome!



Here is the makers page: http://web.me.com/hschlangmann/LapTi...page/Home.html

I guess OBD II support is coming in the next version.

Gonna keep reading up on this.
