Khan Academy user reviews :

This is no doubt the best free learning platform on the internet. But the app still has some improvements to do. There’s a huge lag spike after opening the app. This also happens after opening every course I open. Animation doesn’t show after opening the app for 5 – 10 seconds. It also take something like 5 – 10 seconds to show animations after opening a course. Sometimes it takes about a 2 second lag while opening a category. The courses take 10 seconds to load even after showing animations.

I am a regular user of the Khan Academy app and I have loved it. I uninstalled it accidentally and when I downloaded it again, it refused to open! It keeps showing the message “Unfortunately, Khan Academy has stopped.” Repeatedly!! I have kept deleting and downloading to no avail. I have also switched on and off my phone. I left the beta programme wondering if that is what is making the app lag. Nothing works! Please do something about it.

Best place to learn new things, including academic things, life skills, extra courses, math, etc. The thing that I love the most about Khan Academy is that it does not include any app purchases. So, there are no ads and no paid courses. Each and every course at Khan Academy is better than any other paid course. Special thanks to Khan Academy.

Best app ever. You can learn anything for free, with no ads, every skill, Every topic, classwise and courses too, i have never seen such a useful app with no cost at all, the teaching is great, truly helpful for people in all grades and college year.

I love Khan Academy!! The only thing between you and learning is your willingness to learn. This app proves it. Hands down by far the best app I’ve ever used or come across to help you achieve your academic goals!! I guarantee it!!!! If you want to learn something and utilize this app your learning will be increased 100%!! And your knowledge on the subject will improve drastically. Please take my advice don’t ever stop learning and with Khan Academy this is achievable one subject at a time!!!!!

This app just keeps amazing me, I can’t even think of better education app I have seen my life !!! But if you applied some dark mode it would have been better because the bright white background doesn’t go easy for our eyes especially the web version.
