Khan Academy app reviews

  • Hopelessly buggy app 1/5

    By Orand
    It’s so close to being awesome, yet so hopelessly far. Why is it hopeless? Because of the dev culture of the people who maintain the app. Look at all the Developer Responses to reviews on the App Store. “Sorry for the inconvenience, could you please uninstall/reinstall the app?” You can be pretty sure that if uninstall/reinstall works, they’re going to dismiss it as “anomalous user error” and not fix the root cause for the thousands of others out there who are silently experiencing it too. Bonus points for them: you’re no longer able to give them detailed bug repro steps. These kinds of issues should be fixed once and for all via upgrade, not uninstall/reinstall every single time the app flakes out. Both of my kids experience showstopper bugs in this app that force them back to the website to complete their work. - The math answer entry box runs out of room for text entry, so they have to rotate between portrait and landscape to get more room. - The math entry keyboard stops appearing. Tapping on the answer text entry field does nothing. This could be a side-effect of the portrait/landscape rotation workaround noted above. - Sometimes the “Watch Video” button at the bottom scrolls out of view below the screen. You can scroll up to see it, but the content area is spring-loaded so that when you stop scrolling, it bounces back below the bottom of the screen. If you’re extremely quick, you can scroll way up with one finger and then release and immediately tap the button with another finger as the button is zooming off the screen. You can’t tap where the button is visually, you have to tap where you think the button will be. Again this could be due to portrait/landscape rotation issues that cause resizing of content area bounds. I’d really love for these issues to be fixed because I like putting the Khan Academy app on Guided Access so my kids can’t get distracted by other things like they do on the computer, but that’s where they’ll have to be until there’s a massive culture change on this app’s dev team.
  • Obsessed with this app! I’d even pay $$$$ 5/5

    By Sloppy hoe
    Any free time I had I watched movies, tv shows, anything but learning. I hated learning growing up. Straight F- student my entire life. I used to get so aggravated that I couldn’t keep up with the rest of the class so I would just give up on trying. Khan academy is the complete opposite! It doesn’t make you watch ads or charge you a penny but I’ve learned more in the few days on using this app than I ever thought was possible. The teacher guy that does all the videos couldn’t be better he makes everything so simple. (If you're reading this, thank you very much for how easy you make learning these courses) I’d even pay $10+ a month for khan academy! Thank you very much for all this app has to offer! -high school drop out
  • Developer 4/5

    By Jfhtfht
    Thanks for fixing the app it’s now not frustrating to use. Btw uninstalling and reinstalling doesn’t work often :)
  • I would like to rate it a five! 4/5

    By Nadia1998
    Could be great if you guys added some college classes on here.It would help the college students. But otherwise the app is great and all your videos are great. I understand all of your videos and you guys explain it very well. Thank you
  • Works well for free app 4/5

    By gman91478
    For a free education aid app (and service), Khan Academy is great! I would rate 5 stars, however, there is no way to return to the home screen without hitting the back arrow several times through videos and lesson material. A home button is a basic user interface necessity! Very surprised it’s missing. Also, not all links in non-video material work. Dead links? Bad html code? Something isn’t working.
  • The Real-School 5/5

    By NC2Uangel
    Khan Academy is honestly were I should be paying tuition, but that's the great thing about it it's free. But you should still make a donation, you know keep it free and all.
  • Information=good, bugs=bad 4/5

    By A hopeful customer
    It has great information and layout, but a lot of bugs that effect the use of the app.
  • This app is great! 4/5

    By Cool piol
    The only thing I’d change is that you can see your full profile and how many days in a row you’ve been on Khan Academy. Otherwise, fantastic!
  • SAT Practice?? 2/5

    By Dino322342
    I can only use the SAT Practice on the website. Please put it in the app!
  • website so much better than this app 2/5

    By em0123456789
    The iPad version of this app is missing basic functions like recent topics, bookmarks, etc. A big problem is the handwriting feature for math equations is impossible. It is hard to progress when the app won’t recognize your answer. I prefer the website which remembers where I am and let’s me use the equation keyboard.
  • Keeps crashing 1/5

    By Bear tooth mania
    Please update, the app keeps crashing when I go to play a subject.
  • This is good for finals 5/5

    By Dauntlessash
    This helps me with my first finals that is tomorrow and Friday. I have trouble with fractions mostly dividing them thank you for this app!!
  • Looks nice, doesn’t work 1/5

    By dankenpo
    More than 85% of the time I just get errors saying task progress can’t be made at this time. Seems like a great concept but it doesn’t work so it’s useless.
  • It’s not letting me do any tasks 2/5

    By Dragonxxslayer1231
    For some reason it’s not letting me do any tasks it always says error can you guys fix it
  • Not working out of the blue! 1/5

    By NR's iTunes
    What is going on with the app?! All of a sudden, none of the sections that I tap on can be displayed?! Please fix!
  • No mastery challenges... 1/5

    By audiodelta
    I really don’t like this app...sorry Khan. My teacher assigns a certain number of mastered skills in my grade level, and I’m usually on my phone, so I downloaded the app so I could easily get my skills mastered while using my device. However, the app does not have any mastery challenges. If this component was added, I’d probably give the app 5 stars because that would be all that I’d use it for, but for now the rating will just have to be one star.
  • Amazing App!! ; ) 5/5

    By Sogami23
    This app works sooooo well I love this app sooooo much it helped me how to learn math programming and more in a really fun way I highly recommend this app to anyone who wants to learn. Also it is completely FREE!!!! YAY!!!!🤗
  • Thank you ... 5/5

    By Suhriyye
    Super ...
  • THANK YOU SO MUCH!!!😍 5/5

    By daniel park and jay=love
    I was failing math, till one day I came upon khan academy, my grade went from a 54% average to a 90% average and I passed 6th grade with an A. I am now in 8th grade, but I still use khan academy when I need to understand a concept. Thank you so much I am very great full for this amazing app!
  • Serious update and simpler explanation 2/5

    By HonestGamer893994
    I have been using this app for my high school math and now I am having sudden problems this app is glitching out and won’t let me skip certain problems or the app crashes. This isn’t the only thing, the people that explain in this video are SUPER confusing they have a very.....strange way of exposing things and make things more complicated then it is...they need to see from a different persons perspective, if I am trying to learn algebra the person will use these big fancy words that make you just completely lose it. The lessons are there their free but the explaining and glitching is really getting on my nerves...I kind of want to take back my donation.
  • Lenguaje 4/5

    By Plaslop
    ¿Cómo puedo ver el contenido en español? ¿Sólo está disponible en inglés?
  • We live in the future 4/5

    By Galdutro
    The fact that with this service, anyone in the world has access to basic knowledge is truly astounding. But I have a few wishes: firstly, it would be awesome to be able to download articles and exercises just like videos. Than, the progress made would be synchronized once the device is back online. Also, please redesign the iPad app: used the same interface for downloading content in the iPhone.
  • Two stars for now 2/5

    By Jonaboy110
    The app is great, when the touch input software works, but most of the time it doesn’t recognize when you write the answer. This would easily be fixed if they just add an optional math keyboard input option instead of drawing. I don’t know why they didn’t do it that way in the first place, as a keyboard would presumably be easier to program for rather then fancy AI drawing input that doesn’t work half the time. App is basically unusable until they fix this. I won’t be able to use this app and I certainly won’t be donating money to khan academy anytime soon. And it’s a shame because otherwise the app and education are perfect. Two stars for those.
  • Constant crashes 1/5

    By PureAC
    Crashes every time I press back twice after watching as video.
  • I love the site but... 2/5

    By Ruteeeee
    This app has no clear way of actually doing the practice SAT problems/ questions. All I seem to find are videos and how to’s. The website is much easier to navigate. I only wish the app could be more lit it.
  • Personalize SAT Prep 4/5

    By Kani18
    It’s very helpful but I would like it even more if I could personalize my SAT prep in the app.

    By JoeyLemur
    Please fix the decimal drawing and the answer way in the decimal, 0.3 is the same thing as .3 . So FX THOSE BUGS!!!! Now
  • Hi Dev. Team! 4/5

    By Glitch_Byte
    I love the Khan Academy apps but there exists a problem where I cant *fully* finish a video. Is there a solution for this?
  • Meh 1/5

    By KillJoyGem
    Seemed useful of what I saw but the app froze a lot and took a long time to load, I eventually deleted it because I couldn't even get one exercise finished before it froze and crashed Edit: I have an iPhone 5, I'm not sure what iOS version though, it was just a basic counting exercise on 'Early Math'
  • Videos continuing to play after closing 4/5

    By reviewersb2299
    When you use the arrow to go back (left) out of a video, the video remains playing in the background and there is no way to get it to stop besides force quitting the app. If you open a new video, the old video's audio remains in the background.
  • Khan Academy reweiw 2/5

    By MalakhiS
    KhanAcadamy really helps me with my math so I can continue to grow smarter
  • BUGS 2/5

    By notpleasedwiththesoftware
    I think this is a fantastic app I love everything about it the narrator manages to teach what my teacher takes 4 hours to teach In 10 minutes , but there is this little bug that causes the app to crash after you click on the video if the developer sees this please fix it and I will change my rating to 5 stars
  • Love everything but can’t login with google 2/5

    By beartaco6
    I’ve been using khan Academy for almost 2 years now, it works great on my computer and I absolutely love it. But I can't login with google on my iPad, it’s frustrating. 😡
  • Rate 2 3/5

    By CreatePlot
    It needs to connect with our accounts better so that we have the classes. If it had that then it would update how much we worked on our classes.
  • Marginal access compared to PC 2/5

    By fishie3
    The app has not kept up with the latest iterations of the Khan Academy program. Primarily, you won't get credit for watching videos through the app. The content that is available through the app is less than online. When I try to access KA through my web browser on my phone, I'm automatically redirected to the app. Then to top it off, you can't view multiple aspects of your profile and account through the app. The app has become so useless, that I am deleting it. All of my work will have to be through my computer.
  • Some content missing! 4/5

    By Kayfall
    Khan Academy teaches so many things so well, and it’s free! We’ve been using it in our homeschooling very successfully, but we’ve been forced to rely on the website rather than the app. Sometimes content like Grammar (which is very systematic and fun to learn) is just inexplicably missing from the app. Just isn’t there, not in the subjects listing, nor in the search window. I tried to use it with my ESL students also, but they are also forced to use the website instead of the app due to missing content. So weird!
  • It keeps crashing 1/5

    By BvbbeR4444
    Fix this pls. I have assignments to do that are due today at midnight.
  • It’s good ,but one thing 4/5

    By E3004M
    It teaches concepts well an I am also learning, but make it let us type not write the answer on all devices but computer.
  • We love it 5/5

    By Whydiditry
    We are a family of 4. 2 boys, age 7 and 6, the boys love it. This is the best. Thank you for making it accessible to all. We paid for other math apps in the past but they didn’t have much info and you have to pay for every little upgrade or new things. I understand all apps could be glitchy but that doesn’t mean people should rate it low, It’s on going developing. Thanks again!!!
  • The iPhone app is way better than the iPad appp 2/5

    By Sarahpdc
    The iPhone app does a great job of organizing your downloads by topic and allowing you to download an entire topic at the same time without having ton download each video individually. On the iPad app, you have to download each video individually and then they are not automatically organized by topic which is frustrating. Hopefully this improvement can be added to the iPad app ASAP!!!
  • This is awesome 5/5

    By Bluejaylene
    This has helped me so much I understand more I have been absent and I’m catching up because of this app! Keep it going!!!
  • Just started and I️ have some questions 3/5

    By GirlWith_A_Phone
    Hi, my teacher asked me to join khan academy and she gave me a class code but I’m not entirely sure how to log in with it. I hope this can resolve, my friends have been referring it to me for a while.
  • Love it! 4/5

    By Rumorivateddd
    Thanks to this app i was able to pass all of my college placement tests with ease! I don’t normally rate apps but this one definitely deserves my rating. This app is so easy to use and extremely helpful tool. Equipped with videos, written examples, and sample tests. For all ages from grade school- college. Study for college prep etc.
  • This deserves more credit. 5/5

    By :..L..:
    In no way Is this organization even remotely close to anything other than perfect. This amount of knowledge for free? These people are wonderful. -chris
  • Tasc 4/5

    By Lindasara
    It would be so awesome if the could add a tasc prep section to the app!!
  • Awesome Khan 4/5

    By Dad&girls
    This is a really great site. I can use it for school anywhere. I just wish you could access the Mission page on phone.
  • Trash 1/5

    Absolute garbage
  • Fantastic app 5/5

    By Twochain
    I would suggest this to anyone who struggles in math. I used this app to study for a very important test. I passed with awesome results.
  • “Sniffle nose good” 5/5

    By ip the stunner
    Clean smooth and easy to understand & see. I’m so smart now.
  • Khan Academy Helps to Learn Math 4/5

    By Usernamblblabla
    Practicing math on Khan Academy has helped me to learn new math concepts and it has helped me to reinforce things I have learned. The Academy quizzes you on math problems repeatedly for each concept learned until you have correctly demonstrated your understanding several times. It could be thought of as a math game that will teach you preschool math up to even calculus.
