Good app but

For the people who use IOS devices you need to make it accessible for people to change the language on the app without changing the language of the device it self. Because some people speak more then one language so it would be helpful that you gave them the option to chose their perfected language ON THE APP!

Great learning tool, app needs work

Please, give us a n option to simply type in answers. Some require touch writing, and it’s infuriating to get a complex answer written in their correctly.
Feedback link in the app doesn’t work. Opens a pop up where both submit and cancel do nothing, forcing you to leave the app.
Reached a question where I can neither get hints or skip the problem, therefore I can no longer practice that topic.
I love khan academy, but these little problems can add up to ruin what would be an amazing learning tool

A great (free!) learning resource. The fact that you can download videos for offline is a much appreciated feature.
