Despite having an iOS app for some time now, Khan Academy hasn't offered the full range of course material on those mobile devices. With an update today, though, eager learners can access the company's selection of courses on an iPad. The new version brings 150,000 exercises to the mobile device, with the opportunity to get instant feedback. Khan Academy's iOS software got some slate-specific tools too, including handwriting recognition and a "friendly guide" that observes your response time to suggest activities that'll help you get better at the tough questions. There aren't any plans to bring the app to Android or Windows yet, as the e-learning provider says iPad is its most popular platform behind the desktop experience. However, folks with one of Apple's tablets can nab the update from iTunes now.
