What is Duo View?
A free responsive website preview with an illustrative foldable iPhone Duo model. Paste a URL, explore its layout in 3D or 2D, and compare open and folded views. No account required.
Can I preview my own website?
Yes. Open the simulator and paste your URL. Sites that allow embedding can be interactive when the device is flat. Public sites that block embedding may use a scrollable snapshot captured by Microlink; snapshot links and videos are not interactive.
Is this an official Apple simulator?
No. Duo View is an independent project, unaffiliated with Apple. The model is illustrative and its viewport presets are estimates. Your website renders in your current browser, so this does not replace real-device or iOS Safari testing.
Can I share what I’m seeing?
Yes. Use Share in the simulator to copy a link with your website, layout, fold, orientation, and camera settings. The recipient gets a fresh preview; your scroll position and signed-in session aren’t shared.
