I would type in the sport that you need to help narrow it down. But on an Ipad or Iphone- you can search for free stat keepers for any sport.
For example, I am the head volleyball coach. I use solostats 123 and volleyball stats & player tracker for all of my games.

James,
Go to itunes. They have a lot of great apps for game stats for coaches and teachers. if not have a student or the computer teacher help you set up a program. (just a suggestion).
