The old paid version of the company's content aggregation app, known as Read It Later, has already attracted 4.5 million users. The Read It Later app, now named Pocket, has been saving nearly five items per second of content gleaned from the Web, according to company founder Nate Weiner. Read It Later has been renamed Pocket and is now free.
Pocket's free software for PCs and Mac machines consists of an extension that runs in the Web browser. Free mobile versions of the new Pocket app are also available from the Apple App Store, Google Play -- formerly known as Android Market -- or Amazon's Appstore for Android.
