Khan Academy – a personal favorite of mine when it comes to learning new things for free on the Internet in an engaging way – has brought its full catalog of exercises and videos to the iPad app, updated today.

Nathan Ingraham writes at The Verge:

That all changes today with the introduction of a completely redesigned app for the iPad — now, everything that lives on the site is also available to iPad users. That includes some 150,000 learning exercises, content that product director Matt Wahl said was “where the majority of people spend their time on Khan Academy today.” He also joked that looking at reviews for the current app revealed that adding those learning exercises was something that users really wanted — beyond just the app review, though Wahl says it is overall the most-requested feature for the app.

I’ve already started watching some Microeconomics videos in the app, and I like how everything is tracked in your profile and synced back to Khan Academy on the web. The app makes perfect sense on the iPad as a learning tool, and I can’t wait to start using it regularly. Khan Academy 2.0 is available on the App Store.
