I have buy the app, and make the test on the football team that i coach. The test itself is good, but when i try to see the stats on the boys, there was a big white boks in the left corner and I could not do anything. I try to contact the app producer, but no respons! I have delete the app and re-install it, but now the stats are gone. DONT BUY !!
