Khan Academy app reviews

  • 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.
  • Khan academy 5/5

    By Jadaaaaa.60
    I use this app at school and it is a really fun app
  • I would like to rate it 5 stars 2/5

    By Eugene Ku
    For the concept and the arrangement of valuable material. And I will, once it is rid of the annoying glitches (most of which are connected with the inability of the writing identification algorithm to detect for instance that I’m trying to input O instead of 0, thus leading to incorrect solutions, or the nth root or many other). The app also freezes every now and then. And also it’s impossible to exit review sections (marked with the newspaper icon) other than shutting down and restarting the app. Also 0.5 and 1/2 are the same numbers, but the app accepts usually only one of the options. Etc. The app also doesn’t allow to send in app feedback, - the send button simply doesn’t react. The resolution for IPad Pro is too low.

  • It won’t work for me 4/5

    By howler128
    I go on the app and it doesn’t show my classes like it does on the real website. I don’t know how to get it to my classes. And I really don’t want to have to go to the website just to do my work because I don’t always have internet. Please help me or fix it.
  • Great app now on my iPhone X 5/5

    By rangeix
    This app did crash a lot on my iPhone X but now after the last update it works great.
  • Excellent education, some bugs. 5/5

    By Zenzencat104
    This is awesomeness, I’m learning a lot, and fast from this app, 100% recommend it. But, that being said, it has some bugs to swat, and some subjects not covered, for example: nanoeconomics, architecture, and structural physics.
  • Love it 5/5

    By MoosePrints
    Good to see this type of app available and free.
  • Amazing 5/5

    By Pennyfefe
    Best app ever !!😁
  • Hard 1/5

    By Dave the Awesome
    Insanely hard. Insanely hard to listen but I gotta do school so I have 1,100,000 energy points...
  • Please expand your Endocrine diseases 4/5

    By Xf2007
    Diabetes is not the only endocrine disorder. Addison’s and Cushing’s are also VERY common disorders (infact a percentage of diabetics are actually Cushing’s and after treatment their diabetes disappears). Your site is so wonderful a tool- please allow others who look into endocrinology to access more relevant and real world information. <3
  • Crashes on sign in 1/5

    By rr205
    Cannot sign in via Google. The app simply crashes. No functionality for coaches to monitor progress for the students; need to login to the website which is not optimized for mobile. Wish the app was better!
  • Cannot sign in with google!!! 1/5

    By NicoleHTX
    Just downloaded it and when I tried clicking on the “sign in with google” tab, it just quit the app. I tried delete the app and redownload but still doesn’t work!!!! I like this website but hopefully quickly fix this problem!!!!! I want this app to be on my phone!!!!!!
  • Ugh 1/5

    By baking_queen
    I want to sign in with google but every time I try to sign in it glitches out. I can’t use it now.
  • Doesn’t work 1/5

    By TheFrenchiestFry.png
    I made an account with using my gmail account and whenever I click the red button to sign in with gmail, the app crashes. I’ve tried deleting and reinstalling the app but that hasn’t helped.
  • Coaching on the App 4/5

    By camel
    I think most of the glitches have been fixed, which is great. However, I’m still waiting for the app to offer more for coaches. I would love to be able to assign content and check my students’ progress without having to go to the actual website. Also, please add HSPT to the test prep library!
  • NO!!!!!!!!! The stars above are for parents↖️ 3/5

    By Eliza becknerd
    This is the message to a kit: if your kid this is a horrible horrible horrible horrible if you like to be hundred a week to study then go ahead and use this stupid horrible horrible it does help you with math but the guys voice is so slow and it doesn’t help me with math so I win it’s a horrible app that helps you with learning and I hate Learning😡 but if you were a kid likes learning and likes now and likes all that this is a good for you. Message to parents: this is a great app for kids with learning Dan con Academy has great academics can go from all the way to preschool to all the way to college it’s a great way to learn maybe not the kids favorite way to learn but pretty good
  • Great app for learning!!! 5/5

    By Cha Nó
    Perfect for learning/re-learn. I just wish the app would have a Home button so i don't have to push the Back button every time I'm done with a video/quiz...
  • Please fix this 4/5

    By Jmid14
    I use the Khan academy app on my computer and the keyboard doesn’t work when I am typing in answers. It won’t let me scroll down and it doesn’t respond to the keyboard typing. Please fix all these stupid bugs.
  • Piecemeal Education for my data 4/5

    By NameOfAvatar
    The mathematics review is beyond excellent. Challenges are the best part of this offering. If they work for you, they are a great free review app for the needy student. The auto-play of videos and inability to skip videos is difficult to settle for, but I really appreciate the work the team put in to put this app together. It’s hard not to give a glowing review, even though the occasional bug (error data progress) and need to submit a trouble ticket can leave lasting frustration over systemic hurdles that deplete users’ free time and privacy.
  • Great app 5/5

    By Shdjfhfjfjfj
    Mr.Khan is a god, I won’t do any negatives about the app and the glitches because the purpose of the app does its job well
  • Amazing 5/5

    By enyawt
    Brilliant, just absolutely brilliant!
  • Great app but.. 4/5

    By chelsers09
    I download this app after recommendation of the website. I am an adult deciding to go back to college after many years and need to refresh on a few subjects, mainly math. The app it’s self is great! Very, very helpful! I go through each “lesson” and do the exercises first and if I fail, I go back and watch the videos to see what I did wrong (for math anyway). It is awesome to see where I stand and what I need to work on! My only issue, is almost every exercise I try to finish, it freezes! Then I have to close out of the app and go back into it. It gets very frustrating after awhile! But otherwise, I would highly recommend to those who need help refreshing their mind a little for college! (I can’t say much about anything else as I haven’t had a need to go back that far)
  • Lesson activities unavailable offline. 3/5

    By Matthew pb Smith
    Was hoping to take a few courses when I was going to be without internet access. Downloading a lesson however only gives me the videos. Even though I thought I was downloading the whole course, the activities aren’t available unless I’m connected at that moment. Very disappointed when I discovered that too late.
  • Great content, awful app 1/5

    By ohias
    While the content is excellent, the app is glitchy and barely functional. You’re much better off just using their site. To be honest I’m not quite sure why they even bother with this app.
  • Great app for me! 4/5

    By cat_warriors
    I’m in 5th grade and this app is great. There is a spot on the bottom of the screen when you are doing a quiz to write your answer. So when I try to write, say, (oh and you can’t write letters unless you are describing the unknown) 435 divided by (61-42) and when I try to draw the division sign, it just thinks I’m writing something else, so corrects it. But don’t worry! Just write it as a fraction and you’ll be good to go. Yes, there are some other glitches, like slowness and screen glitches, but I DO NOT press ‘Send Feedback’ at the bottom right corner of the screen because I can’t press cancel or send and therefore have to restart the app. Yes, a great app. Just please, please can you fix the glitches? Please?
  • Want to Love this App 2/5

    By Liz in Va
    It's been a while since I graduated from college so I started using this app as a way to review math concepts before starting grad school. Just to get an idea of how the app worked, I started with the "Early Math" section. The app was absolutely wonderful at first but then I came across sections where I was no longer able to submit answers. I hope this can be fixed soon so I can continue to learn/review!!!
  • Works Great!!! 5/5

    By TBNRSilas
    I am using an iPhone 5c and IOS 10.3.3. I found out it is my assignments that is acting weird.
  • Why no questions? 3/5

    By penislimb
    Whenever I see the topics I go to on my computer I see more question and work then videos, but when I use the app I only see videos . I am tryin to do the work also not just watch videos it’s hard for me to study by just watching .I would also like to do the work when I don’t have access to my computer which is often cause it is incredibly slow and old. Please add this feature, and if it’s there please help me find it I got classes i need to pass and i rely on khan academy a lot.
  • Mostly satisfied 4/5

    By Inkedmermaid409
    It’ll ask me to try again on a question I got wrong then say all the answers provided are wrong. I exited and came back the first few times and that helped but now it’s just frozen there. Would love to have access to this without a computer
  • Oh how the mighty have fallen 2/5

    By Eddie Knox
    Used to work phenomenally with my Apple Pencil and iPad. Now it is so bad I cannot get the handwriting analyzer to recognize ANY variable. Lots of great content on here, and I use it for my job as a home tutor. That’s why it’s two stars instead of one. For the love of GOD please fix or at least give a sheet that shows how to draw variables that will be recognized properly.
  • This is Amazing 5/5

    By Cookiecswrirl
    I love this app, it helped me A LOT it taught me a lot of thing I found confusing I recommend this
  • It's Fine 4/5

    By Satisied Person
    It's a great app but maybe we could type the answer instead of write, can we have an option? For the most part I enjoyed it though, also how the majority of the answers I got wrong were because you mistaken my 7 and as a 2, mistaken my decimal point as a 0 or plan old forgot it; etc, so if you can will you please changed the sensitivity level? Please?
  • Great 4/5

    By Shermyrie
    The app is great but it crashes a lot
  • Education 11/10 5/5

    By Sanatoriuoi
    I really love both the app and the education. First, I would definitely recommend the app, much better GUI and it has much more potential than using the site on a browser. That being said, there are some specific bugs for certain devices, but overall the content is stable and flawless. Second, the education is top in its class. Despite lacking a physical classroom, the teachers on Khan Acadmey have a presence and an uncanny ability to read the room, answering questions you may have about the material inside the video. That being said, Khan Academy is not a perfect replacement for the student-teacher relationship, because you still might have questions after the video. Usually, however, these same questions can be answered through a careful review of the video at either 1* speed or 0.5* speed depending on its length or its speaker. If you enjoy Khan Academy, be sure to check out its unrelated sequels: edX and Coursera. (For higher level education, with some overlap )
  • No sound 5/5

    By Mshakeem
    Hey developers, I am wondering if all the videos are muted. There isn't any sound in any video. Update: it was foolish of me. The app works absolutely perfect. It was in my settings.
