If you’re one of the tens of thousands of customers who pre-ordered the new iPad and you’re wondering what educational app to download to counter the potentially mind-numbing effects of playing Angry Birds HD for hours on end, look no further than the official app of Khan Academy. Released only yesterday, Khan Academy for iPad lets you do exactly what its subtitle says: “Watch. Practice. Learn almost anything for free.”
Khan Academy is a non-profit organization that houses an online library of almost 3,000 educational videos. The topics covered by the videos on the site range from the mathematical subject Algebra to the mathemusician Vi Hart. (Apparently, the site has no videos pertaining to a topic that starts with the letter Z.) And the best thing about these videos is that they’re free. You know, the best things in life and all that.
It took them long enough, but now the good folks behind Khan Academy have released an official iOS app. Alas, the iOS app is available only for the iPad, which is not unreasonable since we’re talking about intensive videos here after all. The app makes the video library readily available on the desktop site even more readily available on the touchscreen iPad. But if you’re worried whether the app would take up hundreds of megabytes and take forever to download because of the multitude of videos it apparently contains, fret not. The app weighs in at just less than 2 megabytes, owing to the fact that the contents of Khan Academy’s entire video library are actually not saved locally. Only those that you yourself download on your device are saved for offline viewing.
The app is suited for anyone with an appetite for learning. Whether you’re a student, teacher or just someone who wants to brush up on Integral Calculus and whatnot, Khan Academy for iPad can help you with your studies, especially once the more than 300 practice exercises available on the site, which are unsupported in the app at the moment, are optimized for the iPad. Khan Academy is available now in the App Store and it is, of course, free.
