I'm used ball'n stats. I think it's good, it's easy to use and understand also if you ask a parent to do it. https://play.google.com/store/apps/details?id=apptimized.android.stats.basketball
But that was years ago, not using any stats program at the moment and because of your question I started searching in the google Play store and there are so many new ones. You can see for yourself. I'm almost sure you will find something you like. Nevertheless I'm following this question, maybe someone had a great tip :-) https://play.google.com/store/search?q=basketball%20stats&c=apps
