Thanks for the reply
Guess I will just have to wait for an update then and just keep use my aging GoPro Hero 2 for 60fps videos.

Sorry for resurrecting such an old topic but I'm having the same issues on iOS 9.3.1 with LapTimer Grad Prix Edition v20.0.1

Posted this on the Harry's LapTimer Facebook page and thought I would post it here as well.

Hi Harry.
Have been using LapTimer for almost 3 years now and I'm really happy ...
