Archir works with any iPhone released since 2018. All you need is a device that supports iOS 18 — which covers models like the iPhone XS, XS Max, XR, and SE (2nd generation), all the way up through the newest releases.
You don't need a Pro model, a special lens, or any extra accessories. There's no premium hardware requirement and nothing extra to buy. The app is built to run on the camera hardware you already have in your pocket, so if your phone can update to iOS 18, you're ready to start using Archir today.
