Tabletiss

Tabletiss refers to a fictional family of modular tablet devices and the accompanying software ecosystem developed by the community-led Tabletiss Project. Designed as an open, upgradeable alternative to proprietary tablets, Tabletiss devices emphasize repairability and modular expansion, with swappable modules for cameras, storage, and sensors and standard expansion interfaces. The hardware aims for durability and ease of maintenance, using common components and a repair-friendly chassis. Typical configurations target about 8 to 10 inches and emphasize long battery life for use in education and fieldwork.

Tabletiss OS is the open-source mobile operating system that powers the devices. It prioritizes simplicity, offline functionality, and user privacy. The software includes a curated app store focused on educational and productivity tools, with strong sandboxing and parental controls. It supports remote management for institutions and content distribution offline, enabling use in areas with limited internet access.

The Tabletiss Project began in the mid-2010s as a collaboration among academics, educators, and hobbyists. In some regions, Tabletiss devices were adopted by schools and libraries seeking low-cost, repairable tablets; however, the project faced challenges obtaining a broad app ecosystem and competing with established platforms. By the early 2020s, development continued mainly in nonprofit and research settings, yielding incremental hardware revisions and software updates.
