You can set up your Facebook settings to text or email you alerts from the website,right? Or is that just for your personal page only? I know I get emails whenever someone likes or comments on a page I co-admin...but I didn't set it up,as I don't have a computer and its difficult to navigate the full site on the phone...so I can't say for sure. But you might want to check out your options if you can't find an app.
