You don't have to be an app reviewer to want to take iOS screenshots. iOS's screenshot feature is fairly rudimentary, allowing you to only capture stills of the entire screen-you can't capture just a portion of the screen, for example, or carry out any other more advanced screen capture tasks. Awesome Screenshot, a $4.99 purchase on the App Store, tries to improve upon the traditional screenshot feature, but unfortunately, it misses the mark.
Installing itself as a system extension, Awesome Screenshot's best use is taking screenshots of entire webpages, not just what's visible. There are plenty of cases where that's a useful feature, but you have to be patient as many sites will load slowly. Also, any active areas of the page are going to render as blank in the screenshot. The app also provides rudimentary editing and drawing tools, similar to Evernote's Skitch app: It's a neat idea, but one that is just frustratingly below its potential.
What's Good: Great way to capture whole webpages on iOS.
What Sucks: Performance issues, not able to catch dynamic content on pages.
Buy it?: If you're looking for a way to get screenshot of entire pages, but don't mind the issues, check out Awesome Screenshot.
