Forget iOS 15, somebody made iOS 4 into a working app for iPhone

It's an almost pixel-perfect recreation of Apple's old iOS software.

What you need to know

  • Someone has recreated iOS 4 as a working iPhone app.
  • It's a pixel-perfect replica with functional apps.
  • It might not fly with Apple once they catch on, however.

An 18-year-old developer has recreated Apple's iOS 4 operating system as a fully working app for devices like the iPhone 12 and we love it.

Developer @zzanehip announced his new app, OldOS, on Twitter yesterday:

Introducing OldOS β€” iOS 4 beautifully rebuilt in SwiftUI.

Zane says the app is designed to be "as close to pixel-perfect as possible", and that the software is fully functional as an actual operating system that you could even use as a second OS, it's also a fully open source project. Not everything works, Messages and YouTube aren't quite there yet, but everything else is, meaning you can browse the web on Safari, take notes, and more.

The new app is available on TestFlight but also looks like it could fall foul of a lot of Apple's App Store restrictions. This isn't the first time someone has tried to recreate old Apple software or hardware inside of the App Store, and previous stories haven't ended so well. This new app isn't even available on the App Store, and almost certainly wouldn't get approval. The TestFlight beta for the app is full but can be downloaded as an Xcode project from Github.

The blast from the past comes just days after Apple unveiled its brand new operating system for iPhone, iOS 15, set to debut later this year. The new operating system features big changes to FaceTime, Messages, notifications, and more, as well as cool features like SharePlay and privacy enhancements.
