5 stars: This is a great educational app! I do three of my school subjects on this, and it makes learning easy. They have great informational videos, and quizzes to apply what you've learned. I also think the app layout is great as well. The ability to pin courses is really nice. One thing I wish they would have kept was the jump to the \
5 stars: Best educational app out there and entirely free. With a bunch of explanatory videos, exercices, step by step explanations. Just perfect. The only thing I want to point out is that the videos get stuck sometimes (but that's okay because you can also watch them on Youtube, where they run just fine) and that the answer windows have bugs sometimes, but that's quite rare. It's still a very enjoyable and incredibly helpful app.
3 stars: I prefer the 2017 version, it was more intuitive an the bugs were negligible. Now I download lesson as before, but the videos doesn't load. And also it's by far slower compared to previous versions (when the logo was a leaf). Hope you fix it :) I love Khan Academy. Edit: I recommend returning to the previous version :( there was no fatal bugs, never, I don't know exactly when, but since the app icon changed, bugs appears suddenly
3 stars: Khan Academy is overall a good learning app, but sometimes the quizzes are really hard and they don't explain how to do them in the videos because they use easier examples instead. And sometimes I would get the answer correct, but it still told me I was wrong...
