All the applications mentioned in this topic play very well the role of saving web pages to read later. Unfortunately Readability, one of the apps we like the most because of its unique functionality, didn't work out the way it wanted due to problems adding new articles and syncing.
Instapaper is one of the most popular, with integration with numerous applications, but it is usually paid ($ 3.99). Evernote, on the other hand, is a very complete application containing many features with a main focus on managing notes through the cloud.
Finally, Pocket is the most popular application that performs this function, with over 10 million users, integrating over 300 applications.
