Does anyone know of any good iPhone apps for track days and/or autocross/solo? Looking for a GPS style that will do lap times, Gs, speeds, etc. Not looking for a pro-timer, just something for a weekend warrior.

I have done some searches but didn't find anything on NAM.

I did find this discussion on another forum about Harry's lap timer but it seems that it may not do autocross (need to look further into it, though):

Sounds promising, but still looking for others.

 

Ok, I found another two:

and

g-tac pro

Anyone try either of them?

 

I use Harry's Laptimer Pro. The pro version does pretty video overlays like this: http://btwyx.com/Movies/InfineonFebBesti.mov

The only bad thing about the Lap Timer is it doesn't log very frequently, only about 1/second. Prior to that I used Rev on the iPhone to do logging, that logs at about 3/second which is much more useful.

Harry's Laptimer has an autocross button, but I don't know what it does.

 

Thanks for the info one Harry's. There is discussion about an add-on GPS that makes it run faster but have not looked into that info. For the track, 1/sec would really leave a lot to be desired. At about 70 mph you are talking about a data point every 100 ft. You could totally miss some shorter corners with that sampling rate.

the other that I listed claim 100/sec. Seems better.

 

I just started autocrossing my Mini this summer and I found "alapHD" on my droid. I do believe that they make this one for the iphone also. So far it has done most everything that I have asked it to, not sure on what the sampling rates are but there is a free trial on it.

 

I don't see an Ap by that name on the Ap store. Not "alapHD" or anything starting with just "alap".
