A Fanzter product, CoolPapers gives you effortless access to over 75,000 iPhone and iPod Touch wallpapers. The goal was to offer fast, intuitive access to the widest possible selection of high quality background images. The UI provides sensible navigation, search, help and download controls. Users can also store and share their favorite wallpapers with friends via Facebook, Twitter and email.

Every team member had input on the final product. And the results are self explanatory: CoolPapers users have downloaded over 15 million wallpapers since launching.

My favorite iTunes review is by Laffinirishman, who writes “Awesome! Works flawlessly…exceeds expectations…Slicin’ Swiss.”
