The OneShot app is the latest in a long line of recently released smartphone applications that focus specifically on Twitter. OneShot targets screenshots, letting you crop, highlight, source and post to Twitter all from within the app. All you need to do is take a screenshot and open it with OneShot.
From within the app you can crop out the stuff you don't want and highlight sentences or passages that are of particular importance. You get to pick the highlighted color, and you can even highlight multiple items. The OneShot app automatically detects the source of the quote and cites it at the top of the image when it's posted to Twitter. Currently, sending a screenshot to Twitter is not a hard thing to do. Still, OneShot does offer more features, which makes it worth a shot for habitual Twitterers.
