As the mobile apps are the easiest and most convenient ways to use the ideas or do something instead of mobile or pc browsers,but guys your android app is lot poor in features compared to your website designing and online features. I have joined your academy some days ago and seriously I loved what you guys are doing and hats off!! to Salman Khan who started it. But as your user as student I would like to inform you about the way you can improve your connections with students and teachers all over world. 
At first when I try to open the email received from you about something like new concepts ,the email doesn't shows option to open in your android app. Secondly your android app doesn't have as features as your website supports,like viewing my profile, in android app I am able to view only my badges and not the option to edit my profile.The User Interface is also pretty poor, so please improve it. You should also allow the option to Discuss with friends in your android app.
These are some basic issues I faced while using your services through your android app,and I hope you guys will improve it in your next update...
Hoping for your next update....
