This app has helped me quite a bit. I feel like I can stay on track and have a free tutor outside of my college classes and refresh what I forgot in highschool. The English and grammar lessons are easy to remember and well built, and although the math lectures can be slow, they make it easy to understand the material and focus on harder concepts one at a time. You can work on the go without having to have a computer standing by, or at a PC at home. Perfect for my needs!

I like it, especially if helping me relearn math I forgot. Unfortunately, it's extremely buggy and actually makes me really angry to have to deal with it so often. Sometimes when I leave a math exercise and come back later, none of the exercises load for the longest time. This wasn't a problem when I started using this app back in October, what the hell did you guys do to it? Also, can't use a hint during a quiz or unit test without it crashing. Please fix these issues because it's really difficult and frustrating to deal with.

The program is fantastic and the lessons are fun, easy to follow, and very informative. I've learned a lot; however, the app leaves something to be desired. The answer box is too small and impossible to scroll, after a certain length, making checking your answer, and even answering, difficult. Please extend the answer box and make it more intuitive!

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 "up next for you" lesson/task button that would allow me to get to my course material faster without having to scroll through all of it. Regardless, still a great app!

It's really easy to use, the lessons are short and easy to understand, the teacher is good at explaining the concepts. The main problems is that once you've watched a lesson 90% of the time it doesn't check that you finished it, and there's no way to manually check that you finished it, so it can be easy to loose track. The other problem is that the app struggles to even work, it wont work out of wifi, and it sometimes won't run the tests even on wifi. Otherwise it would be 5 stars

It's great. I am using it to brush up on Grammer for my field of work but I found much more. Upon exploration, I found useful learning concepts for both my children and myself in mathematics, history, science, arts and humanities. After going through a few videos, I see that they focus on multiple learning styles. Each video has traits of visual, read/wright, and auditory. After the video, they provide quizzes for hands on. It's an amazing resource for anyone wanting to learn.

The app is great! I love that it says the letter and the sounds. The way of teaching numbers is fantastic. BUT I really wish you'd fix the app. Every time my son backs out of the app it completely resets the lesson, (he's 2) and it happens often. I absolutely can't stand it. It's very frustrating because it's a different lesson every time it resets.

I really, really appreciate the website version of this, and thought that a mobile version would benefit me more. However, when I try to actually open a lesson, be it document, quiz, or video, the app crashes. I've tried signing out, clearing the cache, uninstalling and reinstalling the app, and still nothing has changed. Earlier today I sent my crash report to you. I would appreciate an explanation or a solution as I would like to use the app! Thank you!

it's ok, but it lacks a lot of the features of the website such as marking your progress, connect to videos on YouTube, and the discussions. it's just the videos followed by a couple questions without any aid. The main feature it is missing is the discussions where you can interact with other learners, to get additional insight. The discussions need to be included in the app.

So far so good. Brushing up and refreshing my memory on topics I studied when I was younger. One thing I like is the game aspect of it. You get rewarded when completing the lessons. One thing I would like for you guys to add is a green check mark on the course icon when a course is 100% complete. On the app, if you look at the course list, there's no indicator on which you completed. Example, I'm going to do all math, from early/kid to high school. I'd like to see the grade levels checked off.

It's pretty good but.... I wish their was an option to have it read things out loud to the kids, like a little speaker button so it's optional. It would really help my kiddos and me. So far he can only do math on his own unless I can sit and read it too him, which isn't always an option. Also the patent dashboard needs an easier layout. I would also appreciate the option for a 4 digit pin for my kids to log in. And make the app on chromebooks work better. Other than that we love it!

Khan academy/the people/videos/tests are all incredible. Everyones voices are very pleasant,the videos and explanations are quick(much appreciated),as well as very informative and really drives the point home explaining in it several different ways, so it's easily understood, and memorable. The little test along the way really help make sure you understand too. I was ecstatic when I finally completely understood how to solve an algebraic equation! That's never happened before! So thank you!

It's great, just like the website. 1 thing it is missing is scratch paper or notes. I have galaxy note 8 and was wanting to be able to do work within the app. Would be awesome if you guys added this, you wouldn't even need a stylus one could use their finger, it should at the very least be an option, thank you. EDIT: Just realized they actually added scratch paper, and it works just as well as it does in the full website browser. The app to me is now relatively perfect, 5 stars.

I'm on a Google Pixel phone and the videos play fine but the interactivity has some issues. When I tap to see the controls, they either don't come up or there's a lag. When the controlls so come up, some of them don't work. The expand screen button was non functional. Skip ahead barely worked and the speed up/down button didn't indicate any change until I kept tapping it and eventually reached 2x speed. I also didn't receive a green check after watching one of the videos several times.

Love Khan Academy. I preach about it all the time to everyone. Got this app to further my studies. At first it was great. Then I noticed some random senseless lag issues that seemed clientside. No problem, this good material is worth the wait. Today, I just lost about a month's progress in all my courses. It said "We had some problems tracking your progress" and stopped loading quick. Now app shows white screen for a long time. Edit: It is fixed for now.

Thank you so much for this treasure. This app is wonderful. It hurts me to say this, I don't want to seem ungrateful and with all due respect, I have a complaint about the video quality. It has a nice video quality originally but then suddenly the quality drops so bad that rarely, it's hard to see. It would be great to have an option to set for desired video quality. It seems the quality drops based on my network speed but I have a good network that still works fine if the quality is alright. TY

First, I want to thank Khan Academy for their help. I really improved my math skills. KA also added black (blue) theme recently, which is an immense help. But I would like if they made the science courses more organized. RN there are a bunch of similar courses, but it's not clear which is better or why there're a few. In addition some, like electrical doesn't have tests, and a few AP courses have only 1 test per (a huge) topic

Incredible app! Teaches well, and the variety of subjects is astounding! The reason that I'm giving it four stars however, is because all of the videos recorded by the woman took me back to preschool. She talks down to the viewers in a peppy voice, and she started singing about deoxyribonucleic acid? It makes it difficult to watch the videos. Great app otherwise!

Love this app. The lessons are great and exercises actually challenge what you've been taught. I'm probably much older than most people using the app, but I love math (like a game to me). The only issue I have is that some time recently they changed the input and I don't like it. They should also address the issue of nothing happening when you click on a box to input an answer.

I'm a dyscalic adult trying to relearn my math skills. I'm really impressed with the detail it goes into explaining the concepts. How I was taught was mostly rote memorization, but this actually teaches the concepts. I'm still exploring the app, but it looks like it can easily be scaled up or down depending on a learners level and there's a lot of subjects. Great for anyone trying to teach as well. I think the app is a little ugly and not always user friendly. I'd give it 4.5 stars if I could.
