Khan Academy app reviews

  • Best 5/5

    By ibbicraft
    Best app ever I would recommend it. Salam, and allahafiz
  • Just terrible 1/5

    By BladeboyXL
    It may be good for other people but if your in middle school looking for help in math, don’t download this app. This app has no information on what I need help on. It just gives me an exercise. So I became a YouTube guy. Instead of retyping the title of the video and finding nothing, I just go to YouTube and it has everything I need. I wish you could do better
  • The best, you don’t memorize info, you learn it. 5/5

  • Very worth it to Download! Its Free!! 5/5

    By sjennyG
    Im glad i downloaded this App it teaches all subjects and its very helpful! Im glad it’s free because sometimes its very expensive to have a tutor, so the videos that you see here of a teacher explaining every step and solving the problems really help you! There’s all kinds of school Subjects, give it a shot !
  • Please 2/5

    By В Русс
    Developer, when I try to type in “8 5/2, I expect to type eight and then press the fraction icon, then it said eight is in the five place! I have to click several times to just find the place to type in the eight again! So annoying
  • HORRIBLE 1/5

    By dg ccndnnd c
    Worst app you could ever get for your kids. They literally send the parents an email making them tell their kids to do math. It tortures their lives. If you wanna torture you’re kids go ahead get it for them and let them fail everything in math class cause their too busy doing khan academy.
  • Great app but few suggestions 5/5

    By excaliver51
    This is an amazing app and I really can’t find too many things wrong with it but I do have a few suggestions. There isn’t really much space to draw on the drawing tool if you can’t write small. Maybe you can make it so there is more space on the drawing tool and you can scroll down to get even more space. Another suggestion I have is to add reading lessons. If you don’t know what to put on reading you can make us read a book and tell us questions about it later. You can also make us try to spell words and sound them out. For example if the word was awesome the answer would be awe-some, I think, I’m not good a reading or sounding out words. For the videos that teach us how to do the upcoming tests you can tell us strategies on how to remember what happens in the book. You can also tell us how to sound out words and figure out how to spell words by sounding them out. You can also tell us what kind of information to put into our writing when where writing about the book. Ok I know I said I had no problems with this app but I do have one. If you redo a lesson and get a score lower then the first time you did it, it changes your score to the lower score instead of keeping it the highest score. Sorry if that explanation was bad I’m only nine years old but I was trying to say, if you redo a lesson but get 3 out of 5 answers right and the first time you did it you got 4 out of 5 of the answers right your answer still changes to getting 3 out of 5 answers right. I don’t really like that feature and I don’t think others like it too. Other then that problem this app is amazing! Please don’t stop working on it!

  • Take the app down 1/5

    By please take khan acadimy down
    Khan academy stinks my daughter has to get 100% to pass and khan academy is putting strategy’s she not the rest of the class have learned so I am giving khan academy a 1/5 star review!
  • Lifesaver 4/5

    By V3599
    Khan academy has helped me develop a better understanding of the topics that I am currently learning in school. I love how encouraging it is and how I can get a visual sense of how much I am progressing with the app. The only suggestion I would make is that I would like to be able to cross out and highlight the answer choices in multiple choice questions. This way, it’ll be easier for me to select the correct answer through process of elimination since I am learning on a screen and not on paper.
  • Why sign in automatically in Safari? 3/5

    By shiroyume
    It is really annoying. I don't want to this feature. My personal information is leaking without my permission. I love to study on Khan academy site, but the app is not good. I hope this feature will be removed in a future version.
  • Disappointed 1/5

    By Organy
    Why doesn’t this app work. Only parts work for my teen I hope this new update lets this app work. Doesn’t work with my cellular data plan, doesn’t work on my in home WiFi. Whats going on
  • The worst app ever 1/5

    By bye bye kaun academy
    Hi I don’t mean to be mean but your app made my life stink! My mother forces me to do math every night and it made me think it was my teachers fault until tonight... hi sister was doing khan Academy as usual and she didn’t know her answer was correct so she checked with her calculator The calculator said it was right so she typed in her answer and your app said it was wrong! The worst part is our teacher says if you don’t get 100 it does not count so she was super mad and I was super mad too I wanted to get rid of this whole app but I don’t know how I hope you guys take down the app because it really just makes my life hard but thanks anyways! 😄-fake smile!

  • BEST APP 5/5

    By Ashraf Mugalli
    Whoever made this app and made it completely free knows the importance of education. This app has everything from early childhood education to advanced AP college level classes and it’s just mind blowing. I love this app I’ve been using it for years and it just keeps getting better. I learn so much on this app if I don’t understand something that my professor explains, I will for sure understand it from here. There is personal financing, college admissions help, and pretty much anything you don’t Learn in most schools. Thank you Khan Academy!
  • So educational! 5/5

    By Eliana 2011
    I am Really enjoying this app cause I’m really doing good at this app I Love mulptcation so much that is really good and educational this app is awesome!
  • 2x Video Playback is Broken 3/5

    By KungFuPanda17
    iOS 12.4: 1.5x playback speed works perfectly, but in 2x the video will freeze and only the audio will play. Unfortunately unusable for quick reviews.
  • Amazing 5/5

    By Coolnium
  • Solid App, But... 4/5

    By Bpursell13
    I love the app, but we REALLY need an option to disable sound. Every time the app makes a sound, it pauses my music, and I need to switch apps to unpause it again. It seriously messes with my study flow!
  • bad tests 1/5

    By woahsmasher69
    when you want to take a math test for something you get one wrong and you don’t get anything. Even if you do correct it. Especially, when you want to get 100%. YOU CANT RESTART THE TEST? This is bad and your company is bad, 1 star. oh and make sure to do that or else you will get another 1 star :)

  • Khan Academy 5/5

    By Subscribe To Jas GaMiNg PRO
    So, Khan Academy is a very educational app. It helps me learn throughout the year. Even though my school doesn’t use it, I use it. So after all, Khan Academy would be the best app for most people just because it’s useful to watch the videos when don’t understand a question on any homework. But the problem with Khan Academy is that there are something’s that hasn’t been added like Fractional Expressions and echt. But overall Khan Academy is a very, very educational app.
  • Thank god for this app 5/5

    By olivia roos
    Well my grade in math was really trash until I started khan academy. I immediately saw results and I was getting faster every day. So thank you khan academy for making me better at school :)
  • Easy to use, and makes learning easy. 5/5

    By 🍡pastek
    Honestly all of the one star reviews are probably kids who didn’t get an assignment done on time or people who have slow internet and want to play it on Khan Academy. This app taught me how to read music, understand fractals, biology, and more. It helped me prepare for tests countless times. I’ve been using it since the sixth grade and it has never let me down. Thanks Khan Academy for making learning easy.
  • Learn Anything 5/5

    By Tahmsom
    I don’t use the app much, although through YouTube and Khan Academy’s site I’ve experience with the platform, and I have to say that it has been integral in my college courses. The videos, quizzes and text are supplements and at times even better than lecture or PowerPoint files I receive through school. Last semester I passed with flying colors and I relied on Khan Academy absolutely, amongst a few other YouTube teachers. There is no better demonstration of the current era of information sharing than Khan Academy. The app, while I’ve used to a lesser extent (mostly due to screen size of phone versus PC) it is intuitive and easy to use. If you’ve a zest for information, I can not recommend Khan Academy enough!
  • suddently out of app 5/5

    By OaiXeko
    i dont know why its out of app suddently, please fix it, when i watch video inserted into lesson, after a while i happen and make frustating, so i cant learn the lesson wholefully
  • Wrong stuff 3/5

    By pskokan
    I was writing down a multiplication problem and I did 6x8=48 and it said I got it wrong so I did 8x6=48 and the I got it right. But overall I like Khan.
  • Okay 4/5

    By hungryspider
    I don’t hate this app but my dad loves it so he can make work on it over the summer. Which personally it takes a lot of time and energy away from us but, whatever. Sometimes it seems like it’s not fair when you’re working really hard and then you level down. I know it’s frustrating, but most of us tweens and teens know the math is just, I can’t even explain. But hey why go outside when you can make your eyes hurt bye staring at a screen too long. No offense but the scratch pad is crappy. App definitely changed. Anyway my best advice for anybody doing the math on here is to finish it quick because it’s soo exhausting. Anyway great app, but it’s 11:00 p.m and I’m tired 💤 bye
  • 😑 1/5

    By 68Shelby G.T.500
    Can you please fix my problem with the app closing out every time I try to do an assignment. Please, I want to use the app but I can't do anything. Please fix it or at least answer me to more information. Because the app is a bunch of crap.
  • Awesome app 4/5

    By SpaceCowboy86
    Enjoy how it works. Would be awesome if the glitch when having too many downloading in the background causing the app to crash would be fixed. If there was more college course it would be even better
  • Amazing!!! 5/5

    By Tonelli1
    I don’t know what to say but to just say thank you for this, it’s helping me a lot on things I wanted to know. Thank you once again.
  • Unanswerable problems 3/5

    By KaiLondon
    One problem on this app are completely and utterly impossible to get correct for example I had the problem of turning a unit rate on a graph onto and equation, i couldn’t answer it, the answer was y=4/3x though on the mobile Kahn, the only variable it allowed me to put in on this problem was x, I simply could not plug y into the equation, it just wasn’t available. This was not the only time I ran into this problem, in fact it stopped me from get so many mastery points, I’m in 6th grade and trying to prepare for algebra next year, this is not helpful.
  • I hate that you level down 3/5

    By tvhtch uyg hgfvytfcyfvguyg
    Whenever you get something wrong on a unit test you level down on the category that question was from. I like this app but not this feature Otherwise great app! :)

    By falconface3452
    When I first got khan academy I thought it would be really hard was...what is hard +easy...oh! decent, and that's why I love khan academy
  • Better than class 5/5

    By Ang Oso
    Khan Academy teaches better than professors AND I can replay videos over and over till I understand it. I’ll owe my degree to Khan Academy soon.
  • Writing recognition? 1/5

    By Spidey333333
    I used to love writing in answers on my iPad but I don’t see that feature anymore. The new layout of the scratchpad is immensely worse. Also encountered some errors in some of the questions but there is no way to report these. Missing out on a great way to improve this app. I also got 100 percent on several tests and my mastery went down??? Change back and I’d be happy to give five stars.
  • Stupid 1/5

    When I put a equation it always says it’s wrong and I know it isn’t
  • I lost everything of mine... 4/5

    By Jausher6153
    I use Khan Academy on my computer and iPad. It’s a wonderful app for learning new things and helps me a lot with school. I’ve been using the computer programming course for about three years now. On the computer programming projects, you can type to other kids about projects and programming, and I was. I met some nice kids on there and they helped me a lot with my projects, yeah sometimes it wasn’t all just computer programming. We would ask how each other are and stuff like that, but nothing terrible, inappropriate or wayyy off-topic. One day I logged into my account with an awesome idea for a project, when I went back to review some code from my other projects, everything I had ever worked was gone!!! All my YEARS of hard work gone! 😥 I had literally cried so much wondering what the problem was. Then I noticed I was BANNED?! My younger brother tried to get ahold of a guardian, but since you need and email he couldn’t. He tried helping me by asking one of my friends if they could help, but then they BANNED, my poor little brother. He was new to programming and had only made a few projects and I was proud of him. 😔 But all my data from years, my other friend that got banned still had all her projects. They hid every single project and every single comment. Everything in my life’s achievement was there. I asked if they could un-hide my projects or unban my brother but they said NO. Please if maybe I can get my projects back that I lost, maybe I will be more motivated about programming, but this tore me apart! It made me sad to see, my projects from when I first started were gone. My game that had more than 150+ votes: GONE. None of that is replaceable. 😭
  • Trash 1/5

    By Pertty Sad
    This app is a godsend! I haven’t been able to find a more detailed course for mathematics, and this is free!!
  • It’s great when it’s great... but... 3/5

    By Fjjfcvurc
    I like the app because it teaches me how to do things like math. But sometimes it fails to teach me, and the videos can only tell you so much. I am a teen and I’m 13 years old. Now, I don’t want to be THAT PERSON but this app usually adds unnecessary stress to my life and there is only so much I can handle until I explode. From now I tell you the bad parts of the app: 1: Sometimes in the videos it gives me three options to take. The first is the really easy way to solve the problem. The second is the medium hard way. And the third is the most exact answer of all. Now one time I did the hardest way for a fair challenge and it took me longer than 15 minutes to finish it. When I was finished, I was pretty proud of myself and I was sure it would be correct. But when I typed it in it said “NOT QUITE”. Then I got so angry I almost cried! After that I put in the easiest way and got it correct. I thought “ok well I probably just messed up something” so I went about with my day. The next day I asked my parents about the answer and we went through it. BUT THEY GOT THE SAME ANSWER AS ME. I even asked my teacher and he said that is the right answer! So in conclusion, the actual answer was the easiest one and when I worked hard it rejected it... hmmmmmmmmmmm.... 2:The app itself is very glitchy and one time it wouldn’t let me complete the unit test (the final test on a certain subject!) because it said “error computing” I tried again but it said the same thing. Then multiple signs that said that piled across my screen and my phone crashed. You may think that it’s because of my phone but I have a iPhone 7 Plus and that is NOT old! Also It was completely updated... I read some of the other comments and they all say the same thing! “It’s a glitchy app” so think twice before you get this... 3:okay okay, so this isn’t a real problem, but it’s really boring and not fun to learn... Now the good things! 1:it’s a great learning site if you can understand the videos!! 2:at least they try to help anyone with glitches!! 3:it’s supposed to be fun but... Ok that’s it Thanks for reading this! I hope you try it out but don’t rage if you fail because, it’s not you that is the problem...mostly!
  • Horrible it glitches 1/5

    By Gracelynn scholtz
    When I get on the app because it was recommended by my teacher it starts glitching when I go to try to put my answer. I have to wait till I have finished all the other questions until I can retry to answer it for a second time.
