The days of iOS 14 are numbered. Here in June 2021, it’s all about … err, iOS 4?

At least, that’s the case for Zane Kleinberg. While most of the Apple fanbase is focused on the newly announced iOS 15, teen developer Kleinberg painstakingly remade iOS 4 — which Apple released in 2010 — from the ground up as a standalone app. He calls it OldOS, and you can try it out for yourself today.

“What I’ve created [with] OldOS is iOS 4 beautifully rebuilt in SwiftUI,” the up-and-coming developer told Cult of Mac. “In essence, the app is something of an emulator, or perhaps, a second operating system that lives inside an app on your phone. It’s really designed to be a near-functioning, near-pixel-perfect re-creation of iOS 4.”
