Basically subject. I've been following my kid through two clubs over the last few years and there are just a few tools I think the coaches are lacking. One is drill and plan organization, the other is wellness before games (data science). I've been working on an android app for a while now and it's just about to the point where I need coaches to tell me what's wrong with it, or what they like about it.

I don't want to post any links so I can't get called out for advertising, but if you are interested in helping just reply and I'll message you directly. I did get my google developer account approved though I haven't posted a release build yet. There are still a few small issues I need to fix first.
