Thanks to the announcement of Reader for iOS, viewing and interacting with PDF files has never been easier! That’s why we believe Reader for iOS deserves the Mashable Award for “Most Useful App.” Not to mention, yesterday Reader for iOS ranked as the #1 Free iPad App and #8 Free iPhone App in the iTunes store. Although the new Reader app already stands out with its highly intuitive interface and versatile functionality, we need your help to win this award!

Here’s where you come in. From now till November 18,  you can submit a nomination for Reader for iOS in the “Most Useful App” category each day. Once the nomination period closes, Mashable’s editors will select seven finalists from each category, and announce them on November 21. Mashable readers will then vote for the winners.

We’d love your support and encourage you to check out Reader for iOS – if you haven’t already – so you can see why Reader truly is the most useful app!
