About This Software

Your Steam Deck just became so much more than a games console. Zuno turns it into a portable cinema that goes wherever you do. Load up your films and shows and watch them transformed into a stunning, browsable library, posters, backdrops and artwork all in place, built for a screen you hold in your hands.

No accounts. No cloud. No signal. Just hit play. Zuno runs entirely offline, keeping your library yours and in your control, with smooth playback and support for multiple languages wherever you are. On the plane, in the hotel, on the couch at midnight, whether it's a Steam Deck, ROG Ally or Legion Go, your handheld is ready to keep you watching.

Your Library, Perfectly Organized

Zuno takes the mess out of managing media. It recognises each of your drives, builds your library automatically, and keeps everything looking sharp. Every SD card or external drive keeps its own setup, so you only ever see what's really there. No duplicates, no confusion.

Features:

• Automatic scanning — Detects new or removed files the moment you connect a drive.

• Rich artwork and detail — Posters, backdrops and information for every title.

• Libraries that follow your drives — Swap in a different SD card and your library changes with it, so what you see is always what you can play.

• Efficient syncing — Updates only what changed, not the whole library, so it stays quick even as your collection grows.

Press Play and Relax

Zuno keeps things smooth from start to finish. Credits skip automatically, episodes roll into the next, and your spot is saved every time. When you step away, the built-in screensaver fades in with subtle movement that protects your screen without breaking immersion.

Features:

• Automatic credit skip — Rolls past the credits on its own, even on your own files, with nothing to set up.

• Auto play next — Flows straight into the next episode, so a binge stays a binge.

• Resume playback — Come back hours or days later and pick up on the exact frame you left.

• Built-in screensaver — Low-key motion that guards your display when you pause or step away.

Made for Everyone

Zuno speaks ten languages and reads even the messiest filenames with ease, accents, symbols and unusual naming all handled. And because the whole app runs from your controller, you never need to reach for a keyboard or mouse.

Features:

• Ten languages built in — English, German, Spanish, French, Italian, Japanese, Polish, Portuguese, Russian and Simplified Chinese.

• Smart filename parsing — Makes sense of complex and foreign-language filenames, and when two titles are equally likely, it asks rather than guessing.

• Controller-first navigation — Every action, menu and setting reachable from your gamepad.

• In your language throughout — Menus, tooltips and title details all appear in your chosen language.

About the Developer

I built Zuno because handheld gamers deserve software made for them, not ported from desktop. When I wanted to watch something on my own Deck, the only real option was wrestling a desktop app onto a device it was never built for, and it never quite belonged there. So I set out to make something that did: offline, fast, and controller-first, built to feel truly at home on the Steam Deck and other handhelds.

Every part of Zuno was shaped through real use and iteration on the devices themselves. It's built by one player, for everyone who loves their handhelds as much as I do.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Zuno itself does not use AI in its functionality or gameplay.

During development, some parts of the codebase were created with the assistance of AI coding tools to improve productivity and prototype features.

In promotional materials, a few fictional posters and titles were AI-generated to illustrate how a media library might look, since real copyrighted artwork could not be used.
These AI-generated visuals are used only in marketing materials and do not appear in the app itself.
