There is no way to see how many fans you have in the app.

I installed it to try to find that, played around for a bit, and then promptly uninstalled it so it wouldn't affect my team.
Not only do I dislike auto assign, there is way too many steps involved to set where the training goes.. really overall it's nonintuitive, and navigation is painful.. and that was on a tablet, on the phone I'm sure I couldn't manipulate the tiny spots. Yuck.
