Khan Academy app reviews

  • Cool 3/5

    By Jasimawalakakabooooommmm
    I like the app but I wanted to use coding and it’s not even on the app. Please add coding!
  • Great resource for learning 5/5

    By laura03062
    This app explains subject matter in such a way it’s tolerable, easy to learn and refreshing. No obligation to pay, no advertisements nor privacy issues. In dire need of a Khan Academy app for Parents!
  • Keeps crashing 1/5

    By ajjlllll
    Keeps crashing in the middle of math exercises. Driving us nuts!
  • A great educational resource 5/5

    By AlienAnima
    I LOVE KHAN ACADEMY. My kids and I love the different courses and quizzes. A must have for any parent to supplement your kids learning as well as your own (I swear some of this stuff wasn’t thought when I was young). Stay several steps ahead of your kids. Get this app
  • No split screen support for ipad=1 star 1/5

    By Libertarian man!
    This app is pretty fantastic given that it’s free. There’s a plethora of learning topics that are beneficial to everyone...I recently bought a 12.9 inch ipad pro as my primary computer, and was VERY excited to get to crank out tons of khan lessons, and take notes via the apple pencil+onenote. Unfortunately, for whatever reason, the developers have not added support for split screen multitasking, meaning I CAN NOT take notes while a lecture/lesson is open. I’m sorry....WHAT!? This is a HUGE failure and omission on khan’s developers’ part, and has now sent me running to find another site similar to khan to take my lessons on. In my opinion, this is a MUST HAVE feature for their ipad app. Khan devs....please add support for split screen like, yesterday. There’s no reason not to have it.
  • One of the most important apps ever made 5/5

    By mykl07
    This is a tremendous math resource for students from elementary school through graduate school. HUGE room for improvement though for iPad app... 1) have a simple button to report problems with a question. There are several errors I’ve found so far, which are really frustrating. No way to report it easily. Please add this, and only investigate questions that are commonly reported to save you time. 2) fix link to videos that come up with the light bulb... when you click on videos it doesn’t link to the video. Very frustrating, especially for young kids trying to work independently. 3) fix fractions. To write 2 1/2 You should be able to type 2 and then the fraction button to put in the 1/2. On the iPad this is tedious every time to pull up the fractions first and then try to click the right location to put in the 2. Young people may not even be able to figure this out. Not user friendly here. 4) add question and testing content for sciences and not just math. This would be huge for gifted kids, special needs kids and children across the developing world. Okay, pretty much everyone... Please fix these things and this already great FREE app could be much better! Thank you for your hard work on this!!!
  • Would probably get 4-5 stars if... 1/5

    By exwhywhyzee
    It actually worked. No content will load.
  • Everything I know about health, I learned from this app 5/5

    By Gaming Girl Videogames wahoo
    The title pretty much sums it up. I didn’t know anything at all about heart attacks or ADHD or lung cancer or anything health-related before I got this. Love it! 😉 P.S. The grammar videos are great too.
  • Glichy Videos 3/5

    By swEeT PerHeCt2345
    I study art history, so finding out that Khan Academy had a AP Art History course, I was pretty excited. I loaded the app and clicked on a video. 2 seconds in, and it pixelates and the images go blurry. I try loading a different video- same thing happens. I know it’s not my WiFi connection, because I can download videos and files from YouTube and Netflix just fine. I really hope this issue is fixed. I look forward to the possibility of this app, and I really want to use it.
  • Great just one request 4/5

    By nbcamcis
    This is a great app, I just wish there was an option to create other profiles. If there is an option like that I haven’t seen it. Otherwise great app
  • Can’t answer some questions with the characters provided 4/5

    By kpcofgs101
    I’ve used Kahn Academy online for several years. I am now couch bound, so I got the app. It’s a reasonable substitute. One problem is that I can’t answer some of the quiz questions with the limited character set provided.
  • Great math lessons, terrible history lessons... 1/5

    By sky_blue02
    I had used this app in the past for math and it was great for that. The history lessons, however, are atrocious. Rather than objectively presenting the facts, it gives a warped view of things. For example, the authors have somehow figured out how people ‘felt’ during history. No citations. No quotes. They just claim that this person/group felt this, that person/group felt that. I find the personal feelings of past figures to be secondary to learning the course of events. But, if they did feel some need to include them, they could at least cite sources or provide quotes. I saw none. It turned what could’ve been a factual history lesson into some subjective mind-reading of the past. All it was really instructing me on was someone’s opinion of what people in the past felt. It wasn’t educational. Not only is there a bias of perspective — today’s opinion of the past may differ greatly from how people in the past actually experienced it. Opinion and feeling are not the point. It’s history, not group therapy. As I said, if you want to include feelings, at least use quotes, cite sources. But, again, that really isn’t the point. History is not about the feelings of one person or even a group of people, it’s about objective events. Sadly, there was so little of that here, I just deleted the app. What a sad thing education has become!
  • Great app, but some suggestions 4/5

    By beeep bop boop
    We need multitask support and dark mode on this app. Multitasking and dark mode are arguably the best settings on iOS, I think people would be a lot more happy if they could use different apps in split screen and things. And dark mode would just be a nice feature to have.
  • “My assignments” issue 1/5

    By John M. A.
    Whenever I go into past under my assignments, it used to show me exactly what I wanted; assignments for my math class that I did previously along ones that I haven’t finished yet and are past the due date. Now, for some weird reason, it shows me nothing but assignments for some history class that I was in a few years ago. I made sure that history teacher wasn’t still under my teachers, I made sure I wasn’t still in the class for some reason, I signed out, I signed back in, I restarted my iPad, I have tried everything under the sun but I still can’t get to my late assignments! It’s really hurting my grade and I can’t fix it!
  • It doesn’t work 1/5

    By FireKandy
    Brand new iPhone XR fully updated and everytime I try to do anything it’s says error making task progress. Worthless
  • Great 5/5

    By bhvnny_

  • AWFUL 1/5

    By elijah walton
    They give you problems that they do not teach in the videos And they say answers are wrong when you put the same problem they want you to put in
  • Eh 3/5

    By BBows07
    I like the app and it teaches me in a different way that I learn in the classroom. The one problem is whenever I go to practice or take a quiz or test, after one problem, an error occurs and kicks me out. HELP!
  • Please add iPad multitask view on iPad Pro! 5/5

    By BrentAcademy123
    I love Khan Academy! I cannot explain the amount of benefits i have gotten from it. I use it everyday, but please add multitask view on iPad Pro, I will be able to write notes on Good Notes 5 while watching the video. If you do add the support it would significantly help! Thanks ! -Brent

    This is a must download app. It helps me sooooooo much it teaches me exactly like a real teacher does.Has all the stuff you need to learn for FREE
  • Hate this peace of crap plz fix 1/5

  • Major issues 1/5

    By Cjloe12
    I’ve attempted to sign in to my account multiple times, but keep receiving the messages that my password is incorrect. Yet, I know my password definitely is correct because I just created it a few days ago and have it written down. When I’ve tried to put in a recovery email address under “Forgot Password”, it says that an email was sent, but I have not received any emails. There’s no customer service line, so I have no idea how to deal with this issue and recover my account. Very frustrated and in need of some serious help immediately please!
  • Can’t believe it’s all FREE 5/5

    By Nikstress
    I struggle with numbers, in general, and found Khan Academy when I was trying to brush up on mathematics, since I’m training to be a pilot. i found the website first and immediately created an account, and was excited to have an app version as well. The app tracks my progress and offers the next appropriate training when the pre-requisites have been completed. I’m blown away by the diversity of training on offer as well as the quality of the teaching. I’m doing math basics at present, since I missed so much of it when at school, and so appreciate the different ways of teaching that are offered. Thank you Sal Khan, for your vision and determination, and for producing this great app to make all this education accessible to anybody who has an iOS device, and the website for all who have internet access.
  • Sorta good 2/5

    By puppygirl1267
    This has helped me a lot with learning , however it is not that fun. It gets frustrating whenever we get a question wrong, they do not give us another chance. Khan also needs to make it more fun, even though I helps learn a lot, I honestly do not like doing khan because it is boring, and frustrating, but at least I am learning
  • Needs work! 3/5

    By alexisg64
    I love the diversity of things to learn and the videos are very easy to understand and put together. However, there is a bug within the app that does not allow any articles to load. With that fixed it is really a great app.
  • Love this app 5/5

    By Boba Tea Queen
    I use this app in school and at home. When I have a test coming up I go to khan academy and it helps me study.
  • This app is amazing!!!! 5/5

    By AnimeQxeen
    I was struggling on how to multiply mixed numbers this app helped me so much!!!
  • Terrible 1/5

    By desiltc
  • Art classes? 4/5

    By Yorkie 23
    I had a question, could you add art classes that teach you how to draw and doodle. I am homeschooled and can’t find a app that has art classes. I love the app and use it everyday. But, I would love to have a career in art and I need something to teach me. Please include art classes. :)
  • Best of the best 5/5

    By rida mansour
    Really good app
  • It’s not math makes it harder for my kids some of the 1/5

    By martitan F1
    Questions could be answered easier
  • Nice App! 5/5

    By Rebelyfe
    It’s really nice finding an app that’s not trying to pry money out of your wallet from the very minute you open it up lol. Works well m, great app!
  • Good but needs improvement. 4/5

    By Fh kkgccciibbg
    Often lags and freezes. One recommendation is the implementation of the ability to make playlists such that the lessons can be autoplayed.
  • This app has saved our lives! 5/5

    By Aimeeone
    My son needed more one on one help than school was giving him. His self esteem was taking a hit and I was so worried about his future. I was also worried, could I give him the education he needed. I CAN with the help of Sal Khan and the developers of this app. THANK YOU!!!
  • Please adds these features 4/5

    By johnmkelly89
    Search results are a little rough, they don’t always bring up what you’re asking for. Please add photo math to the app, it could even link to videos that could help explain how to work these problems out.

    By Janelians
    I used Khan Academy when I was in high school as practice for the SATs. It was my sole SAT practice resource, I used it maybe 3 times a week in sessions less than 15 minutes. I believe this was the reason I ended up getting a 750 on the English SATs. I am now hopping back on it again as a college ~future nursing~ student
  • Ew 🤮🤮🤮🤮🤮🤮 1/5

    By S A R E E N A H
    this app is really bad. Not in the sense that the mechanics and such are bad, it just really frustrates me when I use it for school. It’s annoying and doesn’t help me learn at all. If anything, it makes me wanna flunk the class instead of doing the lessons and such. Some of the answers are dumb and don’t make sense. Please, make it more boring for us kids at school because it already makes us want to commit die. Some of the questions are non sensical and are really confusing. Making us earn points to get new skins isn’t fun. Nobody cares. I have 32 of these assignments due in a couple of days and I can’t even get through 1 of these without crying in frustration and wanting to throw my laptop and phone out. Once again, this doesn’t help me at all to learn. I’ve learnt nothing from this. All these other reviews from people saying it’s good are crazy. It doesn’t help any of us, at ALLLL. Anyways, I’m just a kid and nobody cares about my opinion. Thanks for making me cry all my tears for the week. I was trying to save them for other school things, but ok. Again, khan academy is bad.
  • Downloading the bookmarks are useless 2/5

    By SpicySosaa
    So you can download lessons but, you can’t use watch the videos or do the lessons offline?? that a bug? or is there something I don’t understand?
  • Very good learning 4/5

    By milo 103
    It is very good but for the maths fifth grade the videos are way to complicated to understand so pls make it more simple . Thanks :]
  • Good but slightly annoying. 3/5

    By vjfjfdkjdjf
    The whole point of this app is so that kids and students can understand and improve their math skills. When you get one wrong in a lesson you have to redo the entire lesson to score a 100%, in my opinion you should be able to go back and do a few questions on the topic of the o es you missed and get a 100%. This change would really help kids grades because they don’t have to redo 9 problems after the make a mistake on one and they problem won’t just leave it at less than a 100.
  • Ugghhh 4/5

    By Please read🤔🤔🤔😢😢😢
    Great app. But wont let me sign in on my account from mobile. Help pls ;-;
  • Checking progress on mobile 5/5

    By Shay Larson
    Are you able to check how many minutes you’ve done on khan academy mobile? If not can you please add it. Otherwise I love the app.
  • Amazing would rate 15 stars👍👍👍 5/5

    By brainiacguyface3.1415926535897
    Great app I’m learning calculus trig and more at a high school level on it and I’m in 6th grade it uses fun videos and interesting articles to help you I would get this app if you like learning or not or or if you are below grade level in between or even above there is always something for you to learn
  • Not enough options 3/5

    By solofoul
    Can you guys make an “order from most recent to oldest” for the past exercises?
  • This works pretty well 4/5

    By DreaB
    I’m a student I mean I still needed an adults help to sign up which was obnoxious but other than that this really helped w/ school 👩🏼‍🔬 (for me at least) I would recommend this to anyone who’s having trouble w/ the program there using now or just wanna try it out
  • Khan academy 4/5

    By shoobah an asem
    It’s the learning tool that truly represent real true accessibility This app is the one that I needed Can you please add alternative text to all images? And for each exercise the back button is un labeled if you fix this I would be happy However I’ve encountered another problem and when I’m working on mathematical exercises when I encounter numbers in tables VoiceOver reads all whole numbers as single digits so can you please fix it?
  • Iphone XS issues 2/5

    By chavoconcerebro
    My Khan Academy app is not functioning properly. With full wifi connection, I cannot access the exercises and the screens do not load. It appears as an “error” on the screen. This is such a wonderful tool that I love to use, especially for AP Calculus. I wish this issue can be fixed soon so I can continue to succeed in Calculus!
  • Once dark theme is supported, this will be a 5/5 app 4/5

    By CancerousOrdo
  • Incredible Content; Mediocre Connectivity 3/5

    By Smitticus 27
    Khan Academy has a spectacular library of instruction videos. I used them last year to study for the MCAT and found that there are no other resources that are even close in quality of content. It’s also extremely convenient to have downloaded videos and text documents on the app so I can study in small bits here and there, e.g. while waiting in line at the barber shop. Khan made a huge difference to my ability to study. Last year I had some issues with downloads and the control I had over WiFi vs. cellular data and streaming vs. downloading the content. I took a break for about 8-9 months and am trying the app again—now I’m having the same issues but much worse! The menus take forever to load and frequently crash the app. Practice quizzes and text documents don’t download (even though they say they do) and require streaming—the only content that download is videos. Download speeds are super slow compared to the speeds I get on other apps—regardless of whether I’m on WiFi or cellular. It isn’t my connection—I’ve tried Google’s internet speed test and also successfully downloaded other content such as Netflix movies through my same WiFi access points and cellular network at my house. PLEASE fix these problems, Khan Academy—your content is too good to be without!!
