Video shot with IPhone 4S and Harry's Lap Timer

nice, what do you use for a iphone mount?

Very nice! Impressive for an iPhone I must say.

That was cool. I haven't been at the track there since the late 70's. I lived close enough to hear the cars on the track. Love that area

Nice......very nice & very impressive for an iPhone use.

How does this work with a GoPro?

Impressive video quality for the iPhone. Tidy driving too.

I've only driven there once so far but looking forward to going back this fall and see if I can improve my times.

I posted pics of mount in "Track" thread under Harry's Lap Timer Pro

The video I posted is video taken by IPhone 4S mounted on my windshield

You can ALSO import GoPro video onto your IPHONE and overlay the Harry Lap Pro data to GoPro video via the IPhone app. I do not think you can export the overlay only for external editting- you must perform overlay on the IPhone. There is a bunch of other drive data you can export to gain insight to your driving. I have GoPro too but find the IPhone 4S HD quality is on par with GoPro- the aspect I really like is the hands free video start- just start up app in paddock it will automatically start filming when you cross the start finish line at speed.

PS - you do have to do the overlay process manually after filming completed but is simple one button action- takes longer than actual lap time but I did between sessions - I recorded 23 laps ~ 2.5 minutes each in HD with ~13GB memory

Here is full session day one- I had a great day chasing down the Roush Mustang
