Reception was mixed, with criticism focused on the shortcomings of the game and its gendered focus and content while praising its clever features.

Pocket Planner is a digital planner which allows users to organize their lifestyles. The game features a calendar, stop watch, phone book, and a series of five short minigames that allow the user to get photos of Mary-Kate and Ashley. The game includes a "Crush Tester" which prompts the player to point the Game Boy at their crush which checks if the feelings are reciprocated and a fortune teller. The Game Boy Printer can be used to print out photos of Mary-Kate and Ashley that are unlocked by playing the minigames. The player can send G-Mail (presumably, email for girls) between users through the Game Boy Color's infrared port. Every screen includes at least Mary-Kate or Ashley though at the Game Boy's low resolution.
