Pocket, previously known as Read It Later, is an application and service for managing a reading list of articles from the Internet. The App is available for OS X, Windows, iOS, Android, Windows Phone, BlackBerry, Kobo eReaders, and web browsers.
Pocket allows the user to save an article or web page to remote servers for later reading. The article is then sent to the user's Pocket list (synced to all of their devices) for offline reading. It even removes clutter from articles and allows the user to adjust text settings for easier reading.
When you save a particular content on Pocket, it is on your phone, tablet or computer and you don't even need an Internet connection to access it.
