Fabularium: Interactive Fiction is an Android app that allows users to create and play interactive fiction on their phones or tablets. Also known as text adventures, interactive books, playable novels, z-machine, glulx, tads, and terps, this app offers a fun and engaging experience for both adults and children.

Fabularium supports all major formats including Adrift, AdvSys, the Adventure Game Toolkit, Alan, Glulx, Hugo, Level 9, Magnetic Scrolls, Scott Adams Adventures, Tads, and Zcode. It even includes a simple integrated development environment (IDE) for users to create their own games in Glulx, Tads 3, and Zcode.

One of the standout features of Fabularium is its support for Unicode games, allowing users to play in languages other than English. Users can define their own keyboards or disable the built-in keyboard to use their system keyboard. The app also takes accessibility seriously, with TalkBack enabled and support for "explore by touch" and "lift to type" technology.
