I did not see when it turned off either time. I just looked up and the phone was in rest mode. It worked great the rest of the day just using the timer. I did see the thread on heat and it was hot, mid 90's. I am going back out Friday and will let you know. Thank you

I just bought the app and went to the track on Friday. The first time I went out I ran the video and it shut off after 3 laps. The next time out it...
