Over the years there have been quite a few screenshot applications out there from BBScreenshooter, to CaptureIt, to my current favorite ZonaSnap. The team over at PocketBerry spotted a new app from S4BB that performs similar to ZonaSnap but also has a premium version that adds more features.
The app is called ScreenShot Free and lets you simply shoot a screenshot and is available at this link in the store. The coolest additional feature is the ability to queue up multiple screenshots to send at one time. It uses the date and time in the screenshot name and plays a sound and vibrates when you take a screenshot. The premium version is available for $2.99 on sale now from $4.99 and adds the ability to set your own options as you can see in the screenshot to your left.
