Beige Box: Tiny Retro Computers for iPhone Duo

Having an iPhone Duo in my hands has already led to another app idea. The new one is called Beige Box: a collection of tiny retro computers you can actually use on your phone.

Pick a machine, type on its keyboard, browse the web, write a little BASIC, or spend a few minutes playing a game. It brings together the chunky cases, glowing screens and little desktop programs that make old computers fun to revisit.

Beige Box is coming soon. As of November 2, 2026, we plan to submit it to App Review today. It is not available to download yet; the release date will depend on review.

Watch Beige Box in action

Here is the first short preview, made with Claude using my iPhone Duo gameplay recording and screenshots from the app.

The moving footage shows tide 00 playing Breakwater, including the last brick disappearing as a wall clears. The other four computers appear as still screenshots in the montage. The preview has music and on-screen titles, with no spoken narration.

A tiny computer app inspired by using iPhone Duo

In my first few days with the iPhone Duo, I wrote about getting used to the phone while building apps for it. Beige Box came out of that same experience: having the device here and thinking about what would be fun to make with its screen.

A little computer felt like a natural fit. The display gives the monitor room above the keyboard and trackpad. In tabletop mode, that arrangement feels like a miniature computer sitting in front of you. Open the phone up and there is more space for the whole machine.

That is what I wanted to explore with iPhone Duo support: giving the extra screen space a purpose you can see and interact with. Beige Box also has layouts for standard iPhone and iPad, so the idea can travel beyond the Duo.

Five original retro computers to explore

The current collection spans the feel of the 1980s, 1990s and Y2K, with five original machines:

• HOMEROOM 82: an early home-computer feel, with a text screen and BASIC prompt.
• STUDIO 86: a monochrome desktop with a compact, quiet personality.
• BEIGE BOX: the family-computer look, complete with a chunky beige case.
• candy 99: colorful plastic and a playful desktop.
• tide 00: a blue laptop-style machine, shown playing Breakwater in the video.

These four screenshots are from the development build in the iPhone Duo simulator. They show the actual app interface; the gameplay in the video above comes from my Duo recording.

Web browsing, BASIC and games inside the computer

The little programs are a big part of the appeal. Surf opens real websites, so the BEIGE BOX screenshot above is this blog running inside a retro computer inside an app. HOMEROOM 82 takes a text-mode approach to browsing.

You can write a note in Write, draw in Paint, and save files to a disk shared by the five machines. The on-screen keyboard is part of the experience, and hardware keyboards are supported too.

For a quick game, there is Worm, the brick-breaking Breakwater, and the memory game Pairs. For a different kind of nostalgia, there is a working, line-numbered BASIC interpreter. Seeing a simple loop fill the screen still makes me smile.

Coming soon to the App Store

We are aiming to submit Beige Box on November 2, 2026. Submission is the next step; it does not set a launch date.

The planned model is a free download to choose your computer, followed by a one-time purchase to use the machines. That unlock covers all five computers and future additions, with no subscription. We will share the App Store link when the app is available.

For now, you can bookmark this preview or follow the blog via RSS for updates. Beige Box support, privacy and terms are already online.

I am looking forward to getting this one out. Having the Duo has made me want to build things that feel at home on its screen, and a tiny computer has been a fun place to start.
