You can use Pocket to put any type of content that you find on a web page in your pocket. This ranges from websites to videos, including the most traditional option: an article. You just have to click the share button and choose the option 'Pocket.' So, you can save the content in question to your account and access it whenever you want, without needing an Internet connection.
Once you start to have a lot of content saved to your Pocket account, you will need to organize it. With Pocket, this is also very easy. You can organize all of the content that you save into categories, so that accessing it is as easy as taking a look at your favorites.
Pocket is a very useful app that will be particularly interesting for users that don't have a 3G connection on their mobile phone. In any case, it's perfect to start saving up a good stock of all of the texts and articles online that you find interesting.
