# Performance Profiling

Work out why an Apple app hangs, drains battery, or grows memory

## What this does

Your iPhone or Mac app freezes, heats up, drains the battery, or dies after running for a while, and you need to know where the problem is. This guides you through Apple's own measuring tools so you can see what the app is really doing. Reach for it when you are chasing a slowdown or preparing a release.

### Top 3 things it does for you

- Track down a hang or a stutter
- Chase a memory leak or steady memory growth
- Speed up a slow launch

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Performance Profiling

Guides performance profiling for apps on Apple platforms using Instruments, Xcode diagnostics and MetricKit.

Covers app hangs, stutters, high CPU, memory leaks, memory growth, out-of-memory crashes, slow launch, battery drain and thermal issues, along with App Store performance readiness.

Also covers adding os_signpost and measurement hooks, so the app reports on itself when you go looking again.

## Questions

### Is Performance Profiling safe to install?

AIR scanned this exact version of Performance Profiling and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit bdf0e83c5d12, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/performance-profiling.

### How do I install Performance Profiling?

Open https://airmarket.ai/app/performance-profiling on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/MengTo/Skills/tree/bdf0e83c5d12c84229b4f9c6524900aca65e44b8/agent-skills/codex/performance-profiling. Install from that link, not the branch.
