Description
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.

Could you build this?
Partial Building a basic 3D folding phone viewer with React is feasible, but crafting a full developer desktop simulator, dual-screen fold-aware SDK, and app execution runtime requires deeper OS/system virtualization tooling.
What it would actually take: Requires an Electron or Tauri desktop wrapper hosting dual webview/iframe runtimes synchronized via an IPC bridge. The hard part is building an accurate simulation environment that handles dual-screen layout shifts, posture events (angle changes), and a reliable sandboxed SDK runtime for arbitrary third-party apps.
