After a long wait and several setbacks, the free Readability app finally landed on iOS devices. Readability is a universal binary that supports both iPhone/iPod touch and has a native iPad interface. According to a blog post announcing the software, the app was born from a collaboration between the Readability team and the talented designers and builders at Teehan+Lax.
It features clean typography from Hoefler & Frere-Jones to turn any web page into a clean view for reading now or later on an iOS devices or desktop with the free Readability browser add-on. Articles seamlessly sync between platforms through an unlimited, searchable archive on the Web.
A paid subscription is still available to those wishing to reach beyond the most recent articles in their Reading List, including the ability to use daily digest of the Reading List on the Amazon Kindle. Early reviews by The Verge and MacStories are positive and it looks like Instapaper maker Marco Arment should worry, indeed (he just updated the Instapaper browser bookmarklet).
Readability for iOS is a free download from the App Store.
