Inspired by Apple's iPhone Duo, Duo is a desktop simulator for exploring a phone that folds. Fold it, rotate it, and build apps for its inner and cover displays with a fold-aware SDK, React UI kit, and App Store. Try the browser preview for a taste of the experience.
Hi Product Hunt! Apple's iPhone Duo inspired me to explore what a folding iPhone could feel like before I could hold one.
How would apps move between the inner and cover displays? What could you do with the phone halfway open? I wanted something I could interact with and build for.
That's the idea behind Duo: a desktop simulator where you can fold the device, rotate it, open apps, and experiment with your own ideas. There's also a browser preview you can try right away.
Duo is built with Tauri, with cross-platform desktop support as the goal. Its developer platform brings together a fold-aware SDK, a React UI kit, and an App Store for installing apps without rebuilding the simulator.
This is my independent project, not an Apple product or an iOS emulator. The apps you build run inside Duo.
It's the first release, and I'm still refining the experience, so expect some rough edges. I'd love to hear what feels right, what breaks, and what you'd build for a folding screen.
