Pocket Binder is an app that provides binding information. Such as step by step binding tutorials, preparation guidance and basic binding knowledge. The app allows users to customize their binding experience by providing information of the book that users is trying to bind.  For example, number of pages, artwork dimension and book type. With the information above, the app would generate the best binding methods for users to choose. The app also establishes a tool shop and binding community for users to purchase essential tools and interact with other binders by sharing their book art.
