Mary-Kate and Ashley: Pocket Planner

Mary-Kate and Ashley: Pocket Planner functions as a digital organizer for the Game Boy Color, integrating utility features with light entertainment. Its core tools allow for personal scheduling, list creation, and contact management, with a unique function to dial phone numbers directly from the device.

Social elements include data storage for personal and friend profiles, with analytical tools to assess compatibility. The software supports sharing secret messages between compatible units and contains an advice feature framed as "Ask Ashley." Another notable utility is the "Crush Tester."

Beyond its organizational role, the product includes four games and unlockable content. Some of this content, such as photographs of the twins, is designed for use with the optional Game Boy Printer accessory.
