Ratings and Reviews
Sharpen your skills with interactive questions and videos.
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
Thank you so much for taking the time to provide feedback on your experience with the Khan Academy App!
We'd love to hear your feedback in detail in our discussion section on the site where it can be voted and commented on by Khan Academy members in order to think about the experience improvement.
Excellent Learning Experince
Excellent and fantastic app! My teacher puts your videos on in class, and it helps me understand so much more work in math. Thanks!
