Free Reaction Time Tree App

Jegs Has a Free iPhone Tree App

Jegs has a very cool Tree app for the iPhone. You can set the tree type and your roll out (in tenths – .31 for my big 11-second 63 Plymouth). Hold your thumb on a transbrake button on the screen — and release for your reaction as the tree activates. I have a big full tree set up in my office and a portatree for the track — but this is just as good, and I can play it at the Dentist’s office. Those with iPhones or iPads can go to the Ap store and search Jegs. Its Free and works great.
