I have used this app as a college coach for a couple years now and have never been disappointed. I am able to accurately view my hurdlers form while zooming and seeing their splits between hurdles all the while. The angular positioning aspect of the app is extremely helpful in getting my sprinters and hurdlers into the correct position. This app has not only made my life a lot easier because I can actually show athletes what they need to work on, but it has actually improved performances drastically. I feel confident recommending this app to all coaches!
