## What it is
OldOS is an open-source iOS app that recreates the look and feel of iOS 4 in SwiftUI, with many functional apps like iPod, Maps, Safari, and Weather that integrate with live device data. It doubles as a learning resource showing how a full OS-like experience can be built with SwiftUI.

## Use cases
- relive the iOS 4 experience on a modern iPhone
- learn how to build complex UIs in SwiftUI
- study how iOS apps and system UI are structured
- use a nostalgic second OS interface on a daily-driver phone
- fork and extend a pixel-perfect iOS 4 recreation

## When to choose
- you want a functional, nostalgic iOS 4 experience on modern devices
- you want a large real-world SwiftUI codebase to learn from
- you want to modify or extend an open-source iOS UI recreation

## When to avoid
- you need a production-ready or officially supported operating system
- you need an actual iOS emulator or simulator
- you require a project with a formal license for commercial use
