About this app

Create and play interactive fiction on your Android phone or tablet. Also known as text adventures, interactive books, playable novels, z-machine, glulx, tads, terps. Fun for adults and also a great way to encourage children to read and develop their imaginations.

Fabularium can play all of the major formats: Adrift (including version 5), AdvSys, the Adventure Game Toolkit (AGT), Alan (2 and 3), Glulx, Hugo, Level 9, Magnetic Scrolls, Scott Adams Adventures (Scottfree), Tads (2 and 3) and Zcode (Infocom). It also includes a simple integrated development environment (IDE) for creating your own Glulx, Tads 3 and Zcode games.

Fabularium supports Unicode games, so if you would prefer to play in a language other than English, no problems! Either define your own keyboard via the keyboards.ini file (see examples in that file) or disable the built-in keyboard via the settings, to use your system keyboard. Keyboards defined via keyboards.ini can have multiple layouts and each key can be programmed to generate one Unicode character, a complete command, or even multiple commands, that are fed to the interpreter one by one. As with anything else in fab.ini, you can set the different keyboards you've defined in keyboards.ini to automatically load with different game and terp combinations.

Fabularium takes accessibility seriously. Much of the app is now TalkBack enabled and the built-in keyboard supports "explore by touch" and "lift to type" technology. Accessibility features will continue to improve over the coming releases. If you are blind or vision-impaired and would like to help me with this (e.g. testing and feature suggestions), let me know.

We care about typography! While the default settings should work for most games, Fabularium is also highly customisable. Make the margins as narrow or as wide as you want. Don't like the default fonts and colours? Change them. Adjust line spacing. Fiddle with other typographical features. Optimise that game for your device's screen. For maximum screen space, try using a hardware keyboard.

Fabularium is and always will be completely free, with no ads, and open source. It does not come bundled with any games; you will need to obtain these separately. There are many games freely available at www.ifdb.tads.org and www.ifarchive.org. You can download these games anywhere to your internal storage/SD card and then add them to your library from within the app. The app is also able to extract files from ZIP archives.

Inspired by the great Gargoyle interpreter by Tor Andersson, Fabularium implements Andrew Plotkin's Glk 0.7.5 spec in Android and can therefore support any glk-enabled interpreter. More interpreters may be added in the future.

How to install this safely

How to verify the file you downloaded

Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.

What the signing certificate proves

Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be io.davidar.fabularium is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.

How to roll back to an earlier version

If the current release misbehaves, 1.5.0 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Fabularium first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.

Why we list sources instead of hosting everything

The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Fabularium, and a listing is removed when the evidence for it stops holding up.
