  • Umm for “cant tell you my name” or something ,,,Ō_Ō,,, 5/5

    By Dgdkwcdjfvfhxndb
    Well if u need help,just go to YT PLS
  • Such a amazing learning app for free 5/5

    By heyolll
    I am in love with the fact that it's a free educational learning app, and this app literally teach you everything you need. Thank you
  • 😒 1/5

    By PeashooterPlayz
    I rate this app still a 😒 because that it doesn’t let you look at hints during a quiz, course test, unit test, etc. due to an error while the practices are viewable which I hate. And second, some practice questions such as the one in statistics “Trend in categorical data” for the percent questions which bothere me, since you only have 2-3 videos about it but none for percent. Now you have to tap a blank spot just to open the graph? WHY.. And the developer responses are practically the same. When I get some answers right on certain questions it just randomly gave me a gray circle (meaning it’s incorrect) Linear Word Problems keep freezing and everything not letting me do anything on it. When it comes to some slope graphing it doesn’t provide me a line (this is fixed) Another thing I don’t like is that you need to show all the steps since in this one word problems question in analytic geometry you had to say one part of it then the equation then you typed the answer I didn’t see how you got 679.. Another issue in interpreting graph examples practice in 8th grade is that you don’t provide a pi button for a specific question and doesn’t accept 1.57 please add the pi button! It’s the only thing that’s missing from the number keypad during the practice
  • Where are my courses 1/5

    By occams buzzsaw
    Maybe I’m missing something but there does not seem to be easy access to my courses from the app. I’d expect them to be listed in my profile like on the PC.
  • The best 5/5

    By mare675
    This app is really the best it helps me so much!
  • Great app, but please fix mistakes! 2/5

    By saraj31
    First, we love Khan academy. My second grader loved doing second grade math until we realized that you made errors! So frustrating for second graders. There are practice problems with no correct answers or answers were you have to choose incorrect answer to get credit. Please fix this soon!
  • Greatful...but 4/5

    By Kk.(Mitchie)!!
    I'm grateful for this app it has wonderful content that is well expand for what I'm using it for and well suited for highschool and college students but I don't understand why there is no split screen support... Is been long enough that most of the other resources like this app have it as well as the iPad pro nomatter what generation, has been out for a few years now.. I enjoy taking notes while I read and watch the course I learn and I generally do that on my iPad pro...I'd apputo have this feature and maybe a text to speech feature for reading the lesson articles.
  • Gets Frustrating 4/5

    By Rustic Coconut
    I enjoy using this app for missed or forgotten basics, however I find it extremely difficult to use on iPhone 6. Correct answer input, yet states not correct. Or not enough area to plug in dots and or animals for graphs and statistics. The movable and adjustable ruler is very difficult to move around. With all that aside, this is a wonderful and amazing concept and grateful it is free of charge. Thank you for that.
  • Teacher’s assignment isn’t there 1/5

    By Sub2PewDiePie77483
    So I don’t wanna do it on my phone since it’s inconvenient so I downloaded the app. When I try to view the assignment, the message “nothing due soon” pop up without the assignment itself.
  • Love the app, wish you can download entire courses 5/5

    By LizS1977
    I love this app. I’m 41 and taking a pre-algebra refresher course. The tutors explain things better and make me think about the concepts in different ways. I noticed that you can download sections of a course, but not the entire thing. Could that feature be added? Can you also fix the ruler widget so it’s easier to rotate?
  • Khan Academy 5/5

    By Batlover2005
    I love how Khan Academy works for you! It’s sooo fun doing all these things in one app that you don’t need to go to your App Store and get app that’s like $5 or more. Some people hate the app well because it crashes a lot on them yeah I feel the same way you do sometimes. Why can they just fix the problem the point is that it takes time and effort for putting good reviews. They just don’t make one or two things in an app no way they do all sorts of things in the app. So if you ever see an app in the App Store that is Khan Academy tell yourself this which app is better? Thank You Khan Academy for making this app!👌😎😄
  • Cool But One Thing 5/5

    By Cool But One
    I’m doing Algebra on Khan. When I clicked on the practice and have a problem needing 2 variables, on the keyboard it only shows one variable.
  • This is annoying! 1/5

    IDK how people like this app Cuz it’s super annoying.It plays happy music if you get it wrong.So this app should go out of business RIGHT NOW!!!
  • Awesome! But.. 4/5

    By CrunchyKnight
    I love this app, when I have spare time at work I can spend it studying. But the only issue I have with it, is it tends to mute my music when I’m listening to it while using the app, and every time I answer a question correctly, the chime sound completely mutes my music. And there’s no way In the app to mute the chimes. Could you please add this feature? I understand you can mute the sounds on desktop, but it does not apply to the app. Otherwise, amazing app! Thank you so much for reading.
  • Very stupid and full of errors. 1/5

    By SeanLee'sRating
    It keep saying I am wrong. For example, I am ratios andI move the dot in the paragraph at the point of 1-3 which is the right answer, but when I clicked on check, it said wrong and the dot mysteriously moved to the point of 1 - 2.5
  • Great 5/5

    By kklop101
    This app is great I didn’t get anything I was learning in class today and this app helped me I absolutely recommend this app
  • Khan academy 4/5

    By Kbrod
    Awesome educational experience for kids!
  • Best thing ever 5/5

    By Mr. HY Wang
    It is fun and educational at the same time. Love it!
  • SAT Prep 2/5

    By Q10143
    My school is having us do SAT Prep with Khan Academy. I got the app to make things so much easier and so I could practice much more. Unfortunately i couldn’t access any prep tests. It took me to the same screen. Where it says to press practice test there is nothing for it on the screen. Please fix this
  • use safari 1/5

    By goldfish432
    if anyone here ever went through the torture of ixl get ready because khan is worse trust me and if you already have to use this for school i apologize teachers should be teaching instead pf khan so what's the point and i wouldn't recommend this app anyway because you can't do mastery challenges so it's pretty much useless if you want to do khan on your phone just go to safari
  • absolutely loving this 5/5

    By apple user for life
    its amazing to see something that is so awesome and helpful free for user its absolutely awesome 👏 love the offline downloads and the selection of features for me rhis is a 5 star app
  • It’s great but drawing graph 3/5

    By huhyhby
    I like that khan academy used the advantage of technology and this is really educational, but what I don’t like is when I am doing a course challenge and there is a tiny graph on the corner and I have to put a few dots exactly on where they want us to. I am fine with that, but I can’t zoom in when I am doing the graphing, because I am actually having a hard time with doing things small so may you have a update so we can zoom in during a course challenge.
  • Very useful for homeschooling 5/5

    By JaidosJ
    It is educational and love to see my kids enjoy learning through this app. I would say it is even better than the PC version!
  • HD download option 5/5

    By IhateElectricity
    Thank you for your effort for creating this amazing app! I wouldn't be able to survive the engineering mathematics course without this app. I usually use this app on the subway so I always download videos in advance. However, the qualities of downloaded videos are horrendously bad and equations are blurry as hell. Could you please make an option for the HD download? I will sacrifice my iCloud storage for a better GPA. Thank you and hope your day is wonderful!
  • Lessons Too Hard 4/5

    By Bmbcvkougccb
    I love this app but... they give you quizzes on things that they haven't even talked about. I can't get past them without using hints which makes it so that the question doesn't count. Please make the videos easier to understand or make the hints easier to understand.
  • make this app more understanding 1/5

    By a.m.h_81
    please make your questions easier to get correct. i put something in a different order and i get it wrong. there is no way to say that i was right so if i want a 100 i have to start over. my teacher always assigns us this for my math class and it is extremely annoying that it takes me over five hours to do 20 questions when i understand the unit.
  • Ive never written a review before but this deserves one 5/5

    By locikam
    im a junior, and im taking my SAT soon. Khan academy has helped SO MUCH with studying and helps me stay on track and get stuff done. Im so happy that i didnt waste money on unnecessary SAT classes when i can just use this for free (also it comes with 8 free practice tests!!) anyways i would recommend this for literally anyone. you learn so much, it doesnt really matter what age you are. i got this specifically for my SAT and ive used it for about a week and i see a lot of improvement already. I’ll be sure to update my scores and my improvement! but if youre on the fence about this app, GET IT!! you have nothing to lose
  • the only thing I have to say 5/5

    By Lrivas1820
    My favorite app
  • Great app that needs a few tweaks 4/5

    By alex7wood
    Edit 2- Thank you for implementing the changes so far! I would like it if you could bring back the undo and redo buttons in the drawing mode so you can delete things faster. Edit 1 - So the update helped a lot, but there are still some areas that don’t register answers. For example, some of the multiple choice questions will not allow you to hit the “check” button. Sometimes when you click the wrong answer it will allow you to hit “check” but then you don’t receive credit for the question. Still buggy with the Apple pen too. I liked being able to enter “draw mode” and to still see the question. Please fix the questions so they don’t move side to side when drawing near them, it’s quite a nuisance. Please fix. Thanks First review - I have a 2016 iPad and the app used to work until this update. Now nothing but videos work. Please fix the bug and the rating will go up.
  • Good but could be better! 3/5

    By carlcarl4
    First of all let me say, I am not rating the content of the Kahn academy here, I am rating the app. The Kahn academy has great content, there just a couple of annoyances that would make the app better. When using the draw feature during the tests, it is kind of clunky. Is there anyway you could clean up the resolution a bit and include an undo button? Also, when you answer a question correctly the app plays a chime. This chimes stops any other audio sources (iTunes, audible, etc.). Is there anyway you could just temporarily mute the original audio, play the chime and then allow to original audio to start again? Thanks!
  • More like dumb academy 1/5

    By GregoryOMGultra
    This does not teach kids well it glitch’s and doesnt say right awnsers
  • Decent, but needs some work 2/5

    By thereviewer516
    I use Kahn Academy a lot, but the app is not optimized for iPad Pro 2018 or the Apple Pencil. I’d be using the scratchpad and doing my work with the pencil and when my hand touches the screen all these scribble marks go where my hand is.
  • Please fix this.... or at least make it obvious 1/5

    By @SlimKnot
    I specifically downloaded the app to practice SAT questions without my laptop.... but the only thing on here are videos which are great but I need to practice QUESTIONS. thanks!
  • REAL BIG BUG 1/5

    By Hiram (Student)
    Khan academy! Please fix this bug please!: I open a Category and then I get kicked out of there! And if I do it fast I still get kicked out!
  • I hate THIS STUPID APP 1/5

  • Boring 1/5

    By nightimex
    This app is extremely boring and bad how is this supposed to interest students
  • Crashes each time I use 1/5

    By zaebalimengall
    I just came across the app and was so excited to use it however I kept crashing each time to the point it got annoying. Please fix the issue.
  • The best educational app 5/5

    By Gobadabadab Monster
    Khan Academy is one of the best apps I’ve ever had. I was just a regular joe who got B’s, then I looked on I-Tunes U for help, and I found Khan Academy. I’m *SO* glad that I found it. It has everything, math, science, list goes on. And the man who is on the videos is so good at explaining and the apps course take is infinite (I don’t have a school that uses it). Now, I’m learning everyday and I’m so grateful that a man made this app. Thank you sir. 10/10
  • 5 yr old 5/5

    By 00sh
    My wife and I do not allow my 5 yr old daughter play games but we do allow educational apps. Khan is my daughters favorite.
  • Amazing 5/5

    By Holy programmer
    One of the best ways to learn when your teachers skip through things very quickly. Covers everything, and is completely free, no fine print (it's also open source)
  • Good learning app 5/5

    By jjinsect
    5 stars for the ability to download courses to do offline
  • One little thing 4/5

    By Moth~Foox
    I just wish that the mobile app shows activity like the website. I do this for homework on my phone, but the screen isn’t wide enough for the website to show up accurately which makes it difficult to check how many minutes I have done so far. If this was added I’m sure other people with this problem would be extremely grateful for it.
  • I hate this app 1/5

    By popsico09
    I’m in fifth grade and about to go to sixth and I must say this app is taking up to much of my free time away. So
  • Excellent but I need it in Spanish 4/5

    By GloICM
    This is a great app but I can’t figure out how to change the language.
  • Best Educational App 5/5

    By Kdangers
    This app is the absolute best at explaining concepts to me that I don’t understand easily in the classroom. My teacher for precalculus was extremely fast and skipped over things, which is why I always went to Khan Academy to get information. It is easy to use and isn’t extremely time consuming either. I am a little confused though how one man can make so many math videos. I’ve never been disappointed with Khan Academy.
  • Terrible 1/5

    By hdqerhhfi
    hate the videos don’t help at all my son did not learn anything
  • Great App! 5/5

    By Crystal331
    The app is absolutely great. The sleek(ish) design, the nice homepage, and the usage is amazing. Though I do suggest you get a separate computer like a chrome book or something. I had to create an account on a separate device and sign in here, I can’t create an account on the app. Also, the characters are cute and nice but I need a separate computer to edit my account, set up a parent account, and customize my character. It’s a bit frustrating but still 5 star app.
  • Khan 5/5

    By furnrhhdrn
    This app is real good but I kneed mAppers
