Thumbylina

Thumbylina is a fingertip-sized life simulation game device designed to be your daily companion. When you set a timer during study or exercise, your in-game character joins you in self-improvement—unlocking new outfits and hairstyles as you progress. Unlike smartphone or PC timer apps, Thumbylina is completely offline, allowing you to focus without any distracting notifications.

This device is developed based on Thumby, an open-source hardware platform the size of a fingertip. Each unit is lovingly handcrafted, making it unsuitable for mass production—but in the future, we hope to create a variety of unique models through small-lot, high-mix production and spark the Thumbylina movement around the world.
