Pocket is a content-saving app that has attracted over 11 million users who have collectively saved over 950 million items. It was originally released as Read It Later in 2007 and has remained true to its promise of "save for later" by avoiding discovery features like trending now or most saved by others. The app's focus on simplicity, ease of use, and user retention has contributed to its success, with over $7 million in funding and a high user retention rate. Pocket's creator, Nate Weiner, attributes the app's growth to keeping true to its original vision and avoiding distractions like paid advertising, which he believes can be hard to justify without a monetized product behind it. The app is designed to make saving content easy and accessible, with features like one-click saves and support for every major platform. Despite being started as a side project, Pocket has become a popular productivity tool used by its creator and millions of users worldwide.
