To anyone seeking to switch from QWERTY to some other layout: I highly recommend Colemak over Dvorak. Colemak is supposedly better optimized, and yet it's easier to switch to from QWERTY since many of the key mappings remain the same.

I switched ~2 years ago because while I could always type pretty fast (I think 80 WPM or so) on QWERTY, I could only do so while hunting and pecking. So typing was somewhat tiresome. Now, I type faster because Colemak is specifically designed for touch typing in mind. And I can still hunt and peck on other devices (i.e. friends' iPhones, or library computers), possibly because of my history of hunting and pecking with QWERTY, not to mention the similarities between Colemak and QWERTY.

Not sure if there's an app for it - I just switched my keyboard and that was that. Initially, I was pretty slow, but my speed quickly picked up. For more info, you should check out their website:
