AppAdvice has teamed up with Cogent in order to offer you a chance to win one of three promo codes for its flagship iOS app, Readtime.

Readtime was the featured app in last week’s edition of Shelf Control, my weekly column on iOS-enabled reading. And as I pointed out in my post, Readtime is an app that can help you get to “reading-list zero.” That is, it can help you get through all of the articles that you’ve saved for reading later.

Currently, Readtime supports two free read-later services, Readability and Pocket. But Cogent says that it’s in the process of beta-testing Instapaper support for paid subscribers of Marco Arment’s pioneering read-later service. So, expect to conquer your Instapaper reading list with Readtime in the near future.

To use Readtime, you must first sign in to your reading list on Readability or Pocket.

Then, you have to set the time for your reading session, which can be as short as one minute or as long as 30 minutes. After specifying the number of minutes you have to spare, Readtime automatically and intelligently fills the remaining time with articles from your reading list.

When you’re finished reading an article, just swipe to the left to archive it and move on to the next article that Readtime has queued up. Each article can also be shared and favorited. At the moment, skipping or deleting an article is not yet supported by Readtime, but Cogent says that it’s already in the works.

Optimized for iPhone and iPod touch, Readtime is available in the App Store for only $1.99. But you can get the app for free by winning a promo code in our giveaway.

To have a chance at winning one of three promo codes for Readtime, just leave a comment below telling us what your preferred read-later service is. Are you more of a Readability person like me? Are you in the habit of saving stuff to Pocket? Or are you an Instapaper user through and through? Let us know, and your answer automatically counts as an entry.

Entries will be accepted until May 23 at 11:59 p.m. PST and will be drawn at random to determine the winners shortly after. Note that for you to be eligible for the draw, you have to log in to Disqus with a valid email address before commenting with your answer. Good luck!
