What is the target level of athlete? Junior high / high school / college / semi-pro / college?

And what does the market competition look like? I imagine there are some other apps that try to do similar things. Or maybe there aren't!

This seems like a pretty fun idea. The stats would probably need some sort of verification standard, which may or may not be difficult to get depending on the sport. You'd likely have to do a lot of research for each sport in each state, for example.
