It's quite okay, for a 'study together' app, however it's lacking a few things that I believe would matter to people who track their studying/reviewing/reading. 1) A statistics page: it's motivating to see how many hours you've poured into studying a specific subject or maybe just your overall hours spent tracking your studying 2) Character customization: There aren't a lot of options to change how you look, and usernames seems to be a free for all at the moment where you can't exactly bind a username to an email address . 3) Different maps/locations: People will want a change of scenery or a different place to sit with friends eventually. It's a promising app, don't get me wrong but it has competition on the app store and on the web.
