## What it is
touchHLE is a high-level emulator that runs early iPhone OS (2.x/3.0) apps, primarily games, on modern desktop operating systems and Android. Written in Rust, it re-implements iPhone OS system frameworks (UIKit, Foundation, OpenGL ES, OpenAL) rather than emulating the hardware itself.

## Use cases
- play old iPhone OS 2.x and 3.0 games on Windows, macOS, or Android
- preserve and run early 32-bit iOS games that no longer run on modern devices
- emulate iPod touch apps without simulating iPhone hardware
- check app compatibility via the crowdsourced touchHLE app database
- contribute Rust code to implement more iPhone OS system frameworks

## When to choose
- you want to run early (circa 2008-2011) 32-bit iPhone OS games on a modern desktop or Android device
- you are interested in software preservation of early mobile gaming
- you want a high-level emulator that is simpler and faster than full hardware emulation

## When to avoid
- you need to run modern 64-bit iOS apps - this is explicitly never supported
- you need to run non-game iPhone OS apps - most do not work and are not a priority
- you expect full compatibility - the vast majority of apps for supported OS versions do not work yet
- you need iPhone OS 3.1+, iPad, or iOS 4.x support - these are only longer-term goals
