One of the best learning tool for any students out there,Its super effective but of course it isn't perfect,There is a bug where some sentences in the Hint button or on the multiple choices doesn't appear at all,Some of the page will just go blank with no reason, It can be fixed by reloading the app but the progress will be removed leaving me frustrated. Need to be fixed but good app overall

the content is so good, but the content navigation is so confusing, too many categories, too many different ways to study the same content. there should be a simplified way of ordering the content, I remember back in 2013 when the math content was so straight forward, now it is such a convoluted, humongous, overwhelming, neverending path that it becomes hard to bare, and I find myself discouraged to even attempt to resume my learning

So far so good. Brushing up and refreshing my memory on topics I studied when I was younger. One thing I like is the game aspect of it. You get rewarded when completing the lessons. One thing I would like for you guys to add is a green check mark on the course icon when a course is 100% complete. On the app, if you look at the course list, there's no indicator on which you completed. Example, I'm going to do all math, from early/kid to high school. I'd like to see the grade levels checked off.

I really like how the lessons are presented and the overall app. Although just after the update i cant seem to tap any lessons. The 'search' and 'bookmark' pages only show a white screen as well. This makes the app nonfunctional for me. I've tried reinstalling it and clearing its cache but both didn't work. Hope this gets fixedd :] for the mean time I'll be using the website instead

Love this app, would give it 5 stars. But it does not like Google pixel 6 pro...when I click on text box to fill in answer it will zoom in...if it is a multiple answer question after the meeting initial zoom in it does not allow to zoom out to fill in last answer...it's like it locks in the zoom and does not allow me to zoom back out. On the PC it's perfect!

I'm a grown man with no college experience, who barely passed highschool. This is exactly what I need to help me prepare for an entry exam for a new trade I wish to enter. No distracting ads. No frills, animations, or alternative learning techniques. Perfect! Please don't change.

Cha. R. Apr 27, 2022     

Everything is pretty great so far, besides one thing that can be a bit annoying. Because it's made like a game where you can earn points by getting answers correct, it bothers me that I can't get 100/100 points, only up to 80/100, even if I've done the practice multiple times and got all questions correct every time. It's just bothersome that I am unable to achieve all the points even though I've done the work and have been successful.

This platform is without any doubt one of the best. But still there are some things yet to be improved in this app. Make the seek button 5s instead of 10s or at least implement a way to change the seeking duration in app settings. It gets way too much backwards if I want to re-listen a part. And implement a pause-resume feture in downloading videos... Thanks for this amazing platform... <3

Geo. B. Mar 22, 2022     

Great app, with great material. One thing I would like to see added though are documents covering every subject, instead of requiring the user to watch videos. On some subjects, there are review texts, which is great, but it would be better if those kinds of materials were available for all content.

Sam. A. N. May 11, 2022     

It is a very good app , it contains all that I need, but when downloading a video from bookmark, it promptly say error downloading video from bookmark. Please figure it out in your next update.

Al. H. I. May 11, 2022     

Great app but I'd love an option to read lessons rather than watch a video. I don't mean captions rather a text book format; if this option exists I definitely haven't found it.

rit. p. Apr 18, 2022     

Increeible, very well explained and thorough. Love this, it's a great way to learn something new or complement your studying (I did the statistics course parallel to the one I'm taking at uni and it was a great help!). Also I did it in english, but the translations I saw were very very good (for portuguese and spanish)

It is an amazing experience to learn through Khan Acsdemy. The best thing I like about it is that, Khan Academy teaches through these interactive videos which explains 'Why' questions which I think is very important for kids to answer them. Moreover, we can learn anything from anywhere at anytime at our own pace which is the most beautiful thing about online learning. Khan Academy is the best!!

Kev. A. May 15, 2022     

The app is great, let's you pick your courses and such. Also you can get 100 points on every course if you get 100% on the unit test. Charlie must have just started. Basically the unit test is 20% of your grade.

Ang. W. Mar 4, 2022     

Good for learning however the videos are super long and confusing, such as they hold so much information some people just can't store it in their brains. and it would be nice if the mobile version had noise... it feels creepy compared to the computer version.

Gra. B. Dec 22, 2021     

So I love Khan academy, and it's a great learning platform, but it's so annoying when I try to answer something then get and answer wrong, but it's at the beginning so I have to finish it instead of restarting and trying again. So I think because of that, there should be a restart button for any of the problems you have to do. Other than that I think this is great.

Ebu. F. Apr 28, 2022     

This is a mobile data killer. It's quite sad that I have to keep downloading video over and over again because whenever the screen backlight goes off I'll have to restart download afresh. It's painful, discouraging, annoying and heartbreaking, especially for someone like me who has to spend through his nose to buy data in a 3rd world country. I am seriously disappointed!

ble. e. May 5, 2022     

It's what I'll describe as the perfect way to teach... The quizzes after each topic and the overall course mastery test it's amazing and it's what I've been looking for in forever thanks to y'all for making this app and making it free you're teaching me more than what I've learned in school and I really appreciate it

DIA. K. J. Mar 5, 2022     

I like the app for educational purposes. Unfortunately the app isn kinda lagging (not really that much) but i think you need to optimize really well especially for who uses a device (like a tablet or a phone). I'm not forcing to do this if you can't then that's fine but i do need a reply if you can necessary.

It's been a great experience with Khan Academy. It needless to say how this platform is helping a vast majority of students. The application is nice enough. But it would be more convenient if DARK MODE is available. I hope you'll take my suggestion into your consideration and implement this feature in no time. Thanks.

Wil. Dec 20, 2021     

The content itself is 10/10, no complaints there. Khan academy is an excellent learning resource. The app however is merely servicable. Its slow to respond and becomes nigh unsusable (at least for me) with no access to a dark mode option, that I can find. Looking forward to future improvements.

Ela. W. Apr 12, 2022     

This is just AMAZING! 5 stars without a doubt! This is amazing In every way i totally recommend it!!! It helps me A LOT with my home schooling & is one of my favorite resources to use! It makes school fun & easy to understand! It's Very easy to use & so helpful! The app works so well, all the resources & tests are super helpful, i love it! I think it's so good for home schoolers like me & those who just need to reinforce & better understand different subjects! Amazing job, thank you!

Not able to load tutorials, Although I love Khan academy and it's teachings (would rate 5 stars) , I will rate it as 1 star atleast for now coz the courses are not getting loaded and gets freezed up into a white screen after opening the app, I've tried all the basic trouble shooting stuff but still unsuccessful, kindly please look into it and fix in the next update

R.C. P. D. Mar 31, 2022     

Really explains every single subject with engaging videos which talk straight up to the point and is very very simple and easy to get through any concept in the selected course...I prefer everyone to download this free app which can clear concepts and I think can make a backbencher a topper in no time...Use this app and I give it 5 stars⭐⭐⭐⭐💫💫

Abd. K. Apr 1, 2022     

Freaking out !!!!!!! Well the content Khan academy provide is great and I have been using it since 2020 and got to learn a lot in my high school but now after this previous update I think that there is something wrong with the app as whenever I try to open the app it takes so much time and wait there isn't any issue neither with internet connection nor with the device ... please do correct this....

Cod. T. Mar 30, 2022     

This app is amazing for education! I am doing the SAT Test Prep and it has given me a huge insight into what SATs are supposed to be like. The only problem I'm facing with the app is loading time. In addition, I would like recent lessons to be removed from the home page if they are checked as finished.

THE. W. Mar 19, 2022     

Getting to have 100+ free courses with no in app transitions unlike other apps without time limit is absolutely stunning. I thought itd be having a free trial abt a week or 2 but no its completely free.The only thing needed is a internet connection and ur done. Thank u for such a wonderful app.😍

Tha. Apr 21, 2022     

Its a great app, but sometimes I have issues where if I need to scroll down to view a whole problem it won't let me scroll anymore and it's cut off. I'm using an Android. Not sure if this is just an issue on phones only and if it works better on something like iPad

C.L. C. Mar 23, 2022     

It's been the most vital fortnight before uni and you guys still haven't fixed the issue. Blank screen. Nothing shows except the background. I can not use your app and I need it to understand linear algebra. Samsung A2 core. My internet connection is fine. Please fix. And 2. Stop telling everyone with an issue to report a ticket. This is my ticket. We're not here to chase it up for you. I'm miffed without Khan on the phone, but I'm not gonna die if I can't use it. Take or leave my review.

J. W. Mar 15, 2022     

Amazing app! 👏 This app was a great help to me while preparing for college and I still use it. There are a lot of subjects and they're explained in a way that's easy for me to understand. It was always difficult for me to focus in a classroom setting so this method of learning is perfect!
