Ratings and Reviews
Khan Academy is an education app for everyone—whether you’re a parent helping your first grader with geometry or a postgrad looking for a deep dive into microfinance. If there’s a topic you want to learn about—no matter how basic or advanced—chances are Khan Academy has a video lesson for it.
Finally a completely free app! I really love the effort your team made to offer as such a nice app. Really helpful Thank you <3
Great content, sometimes it lags
I love khan academy. It has helped me with some college courses and now I use it for personal reasons. It has great content and all for free. My only issue is that sometimes when I open the app all I get is a white screen and I have to close it and reopen it.
