Awesome lap timer

I use this app to review my autocross runs during every event. The video with overlay is valuable info and very cool to watch! This app is a big factor in why I switched to iPhone. Works great with the recommended Dual XGPS150a, although an occasional reboot of the iPhone and GPS is needed, I think the external GPS is at fault but cant say for sure.
Keep up the updates and great work.
