The app is bad because it shows you a video on how to do it the makes you do the complete opposite in the practices.
You need perfection to pass. Poor child cannot get any wrong or she had to retake
Overall, Khan Academy is an amazing idea. I’ve been using the app for years now. This means that I have been through many many many updates. Khan Academy has gotten to a point where I cant even figure out how to navigate through the app. There are some new things about it that are just dumb now. My least favorite part is the scratch paper. When you are finished and go back to the normal part to submit your answer you have to go back to the pen to see it again. The wort part though, is the eraser. The size is way too small. Instead it should be adjustable so that it doesn’t take ten minutes to erase your work and start again. I think that Khan Academy should have just kept the same layout that it did when I started using the app in 2014.
Please, could you fix this? In the meantime I’m using the website because I can turn off the sound.
Protractor does not rotate
So the app is good in general. It has lots of courses on lots of different skill levels and it’s free.
Khan Academy is a wonderful app. I have only one complaint, it is that the coordinate plane is too tiny. I can’t really see the numbers too well, so I end up making something strange. So, please fix the size!
KHAN ACADEMY PLEASE BRING BACK MASTERY CHALLENGES FOR THIS APPP!!!!!
This app promotes a world view different than my conservative Christian world view
This app is great and i have been using Khan Academy for 4 years already.I use Khan Mappers AND Khan Academy.It has been helping my education a lot and I’m only 10.The only thing is that my teachers tell me to do 45 minutes of Khan Mappers but when i time 45 minutes of non stop work and i go to progress it says I’ve only done like 37 minutes.(weird).But still great app and i would recommend this to anyone under 18.I like the energy point system since you work towards something rewarding.Ive done all courses except for the senior ones.Thank you Salman Khan and the Khan Academy group.🥳🥳🥳
I’m a big fan of Khan Academy but not when nothing loads. I went into the app and none of the videos and exercises loaded, I updated the app and the same thing occurred. I then deleted the app and tried again but it wasn’t even letting me sign in. Any help would be greatly appreciated.
Can't update or download app! Please fix this!!
It’s great app if it work, but for me always shows error and have to stop it and download something else for my daughter
Khan academy still doesn't have split view support; disappointing. I hope it's in the works soon. Split view is a feature that will greatly supplement(actually essential)the learning experience for your students wishing to do digital/paperless notetaking on the ipad. Having split view will allow students to simultaneously access both the learning materials and then be able to take notes at the same time like a real classroom, it will help with engaging with the material better to help better and more comprehensively remember as notetaking is an active process. I know personally it will help me as a student to engage with the khan academy app/course materials more as it increases usability(and situations) and user experience. An example I was can give of the split view feature positively complementing khan academy app in action would be of students taking math courses in khan whilst having the app split together with a writing app(note app, whiteboard, blank scribbling app)this writing app will be used for maths working out and upon reaching the answer be able to immediately submit into khan academy app for answer checking; this ensures studying/learning/taking classes without losing or breaking any nice work flow, a seamless using experience...I hope to see support for split view soon on the horizon. Thank you!
This was really helpful if you want to learn how to do maths. The instructions were clear and the videos were helpful. Just wished the playlists and tasks weren’t so long, but this was a great app! 👍🏼
In algebra I, in the equation box, only 1 variable can be entered, not 2. For example, instead of entering ‘d=x-5’, only ‘=x-5’ or ‘x-5’ can be entered, which is not a complete answer. And, as a result, the system will respond the answer as incorrect. It should be fixed at the earliest convenience.
Topics are extremely useful for high school student especially for math, chemistry and biology. However, it would be even better to have lessons in notes rather than video sometimes, for more convenient.
This app is so much better then mathletics
The app is way better now since yesterdays update! Support for iPad Pro 2018 is finally here 🎉 and the app just looks a lot better. However, we’re still missing keyboard support for video playback controls (i.e. play/pause, skip, rewind, and that good stuff.) plz can we have. Plz plz plz. Otherwise, I’m very satisfied with this update.
This is a great app. I got it to try and revisit some math and science subjects I learned a long time ago and to learn more advanced things and have been very impressed. Sal is a great teacher, very good at breaking things down so you can understand the why along with the how which I feel is very important.
I’m so in love with Khan Academy, and I’m so grateful for it!! It’s really simple to use, and it has all the subjects that I need. And it’s free!!!! I am a foreign student who recently moved to the US, and I just started my first semester at cuny as a biology/premed student. Biology is hard, especially that English isn’t my first language. The textbook is really hard to understand and I have to translate most of the words, but Khan Academy made it so much easier for me. The language that the professor uses in the videos is really simple and understandable, yet academic and professional! The best thing is that when I don’t understand something, I can repeat the videos as many as I want!! In addition, there are articles about the same subject that I can read after or before the video! I just want to thank everyone in Khan Academy! You guys are the best!!
Lessons are simple, and tests are short. They're just barely long enough to prove that you know how to do something. You can take them as many times as you need! A little sad that my progress was erased after making an account, instead of applying my current progress to it. Fortunately, I made an account soon after finishing a section, so I didn't lose too much progress. So make sure you make an account right away!
Great app , I have iPhone 7 , every time open this app or close it my iPhone restarted, Sometimes hang only inside app , other thing great. Go on
if you google something and click a link from the search results, you are taken to the apps home page, not the article you clicked on
Content is great and helpful but can’t solve any problems since keypad doesn’t allow variable input, only digits
Ok this app is great it is wonderfully informative and has helped me learn so much. My only issue is the eraser. You know the one when you are writing out your work or something but then you make a mistake and have to erase to fix it. The writing part of this is perfect but the eraser is way to small. Like incredibly minuscule when I’m trying to erase some work to make more space and I’m working with an eraser that barely makes a dent in the markings. But like I said the rest of the app is amazing and I thank you some much for making it.
First of all I love Khan Academy and it has been extremely beneficial my learning and a lot of those I know. I like the design of this app but, there are sevral features that are not perfect. The feature of being able to play back the tutorial videos at different speeds is possibly causing the audio in the video to be distorted, and the video and the audio become disconnected (the video looks to be playing nice but, the audio stutters and some words seem to be completely lost). The feature of quizes is great but having a small screen (4"), which makes it so that at least for some of the practices, I have to scroll to see the entire question, and toucing the screen causes the cursor in the answer box to start selecting different things. Then the combination of small screen and possibly my old device may have caused the lag from the quizes to cause the app to crash sevral times. Along with the quizes I noticed, at least briefly that some progress wouldn't sync between what I did on the computer and what I did in the app. The home page, the one with all the courses, takes a bit to load, almost every time. A side note, about the app, the programing course should have a label or something saying that it will open the course in a browser, and that may actually not load depending on the device's capabilities. Also, please add the feature of the forums that are at the bottom of most of the videos and articles, like in the desktop version of Khan Academy. Along with adding the forums, it may be beneficial to add the forum feture to the quizes, just in general. The feature of seeing your own streaks could be really cool in the app. I think this app is still a great way of learning from Khan Academy, it's just that my device probably can't process well enough. I like the overal design and workings of this app but, to work on iOS 9.3.5 and screens that are small (4") I think a little more coding has to be done. So, it'd be really beneficial to at least fix the video play back and the quiz laggyness problems in the next update for iOS 9. Thank you.
When I answered a questions topic alright it says that I hv to try again. Why? Khan academy is mean especially when I have to answer these questions. Please fix this right now
My child so much like that she can do a 12+34+56-1 an that is hard but she’s not really learning anything about science!
The app will no longer open for me, this has happened since I updated to the newest version.
I honestly really liked it I love how it shows you how to do it and it gives you questions about the topic amazing 💜💜
I can't change the language! I can't do anything... there are an option, but doesn't work.
The app crashes every time I try to open the "plant biology" section. No issue if it's "human biology"...
Hello,khan academy staff. Your videos are very helpful. I have a request if you could do key stage 2 videos. I am taking the test next year. Could you do the book Year 6 plus targeted study book please.Thank you.😃
You can't answer any problems and can only watch videos. Please fix this soon
I can't access my profile notifications or to change my picture
I downloaded this app because we are doing it in school. But when I went into it, I wasn't able to solve math problems! All you could do was watch videos. I was very disappointed when I found that out. Otherwise it is a brilliant app for learning.
Get this app this app will help you if your stuck on maths of anything to do with maths get this the best thing is that it's for free!!Now I know all the knowledge 🤓🤓
This app is the best for studying everything and the best part is its free its just great especially for science you learn so much in every segment its just really great download it now🤓
