“Nano Note” is a Japanese Game Boy productivity cartridge designed as a digital personal organizer. It transforms the handheld into a multifunction device, offering features such as calendar, scheduler, address book, memo pad, calculator, expense tracking, alarm, and even simple fortune-telling.

Marketed as a “Game Boy electronic notebook,” it reflects an early attempt to position the Game Boy beyond gaming, aligning with the broader early 1990s trend of portable digital assistants. The packaging emphasizes everyday usability and even communication via link cable, highlighting the ambition to turn the Game Boy into a practical lifestyle device rather than just a console.
