Castle is a free multimedia application available on iPhone developed by Montereys Coast Inc. It allows users to create and play interactive cards. With Castle's small but powerful editor, users can bring their digital cards to life with touchable and controllable elements.

The program offers a wide range of possibilities for card creation. Users can design cards that serve as toys, scenes, stories, tiny worlds, animations, or simple doodles. These cards can be combined into decks to create immersive worlds or to tell dynamic and branching stories.

Castle also provides a community aspect, allowing users to browse a feed of new and popular cards made by other creators. Users can follow their favorite creators and receive notifications when new cards are released. Additionally, users can build a unique profile that showcases the cards they have created and played.

Creating cards in Castle is accessible to anyone, with a simple yet robust drawing tool that includes shapes, layers, and frame animation. Users can then bring their drawings to life with motion, physics, behaviors, rules, and sound effects.

While some features in Castle may require in-app purchases, such as featuring extra cards on a user's profile, creating and sharing cards does not require any additional purchases.
