Android: If you're looking for a good reason to root your Android phone ShootMe is the easiest to use Android screenshot—and screencasting!—software out there, but you'll need a rooted phone to take advantage of it.
We put the disclaimer about rooting right out front so you wouldn't be disappointed after you read on and discovered you needed to root your phone to get at ShootMe. If you need to do any screenshots or screencasts of your Android phone however it's a fantastic app and worth rooting for—it's actually the reason I rooted my phone.
You install ShootMe, run it, and in the default mode any time you shake the phone for more than half a second it snaps a screenshot. You can hit the Menu button when the information screen is open—visible in the screenshot above—and adjust your settings so that ShootMe will snap a picture when you shake, when you shout—it works well, even if you look and feel silly yelling at your phone to take a picture—or you can set it to shoot in "movie mode" which is actually a string of successive JPG images snapped at rate of a couple hundred per minute that can be strung together to form a movie using a tool like previously reviewed PhotoLapse or GifNinja.
You can search the Android Marketplace for "ShootMe" or scan the QR code at right to grab a copy. Have a favourite Android app to share? Let's hear about it in the comments.
