Khan Academy is an education app for everyone—whether you’re a parent helping your first grader with geometry or a postgrad looking for a deep dive into microfinance. If there’s a topic you want to learn about—no matter how basic or advanced—chances are Khan Academy has a video lesson for it.
This app is absolutely fantastic and I want to make it clear I gave it 4 stars only because I personally have some things I wished would be added to to make this app better. Like for instance videos that are not drawn out by hand, don’t get me wrong this is a good visual sometimes but sometimes I feel the visual falls kinda short to if it was either animated or demonstrated (specifically for the science lessons especially). That being said I want to be clear, that’s all fine tuning for the perfection of this app. This app has helped me learn soooo much and it’s completely free. Most all of the teachers are excellent and the fact that this is videotaped lectures means you can watch anytime at your own speed. I wished things like this were used more widely and familiarized in my state (not that a lot of people don’t use it already cause they do, I just wished it got pointed to if nothing else more as a sort of in general go to guide among other similar programs by schools and government PSAs more.) but that’s not this apps fault. My hopes is that some elected official somewhere will see this comment and this will give them the idea to make this more second nature for people to pick up somehow via PSAs etc
What an incredible app. I’m so impressed. This company deserves loads of money to be thrown at it for making it free. My son has just switched from a Cambridge school to an American School and missed a lot of work. I think we were both about to give up. I didn’t know where to start to help him and being his new school is completely iPad based we felt deep despair at just the thought of trying to navigate through classrooms codes and half working text book apps. Now it’s all here in one place! Simple well explained and the practice really gets your confidence going. He had some maths homework and instead of the total melt down we both would have had trying to work out what was going on we flew through it!! THANK YOU! I love the fact that all the grades are here too so if there is a concept he is struggling with we can go back in the grades to see where that was introduced and work through it! We have been struggling for months trying to find the answer on line. It was only due to the fact that Khan kept coming up that I googled it and found the app. I truly pray this company gets loads of financial support to keep this app going! THANK YOU THANK YOU THANK YOU!!
