Axiom Hang Diagnostics

charleswiltgen/axiom
180 installs1.1k stars
Summary

When your iOS app freezes and users see that dreaded "App not responding" dialog, this is the skill you want. It walks through systematic diagnosis of hangs, those moments when the main thread blocks for over a second and nothing responds to touch. Works with Xcode Organizer hang reports and MetricKit diagnostics. The clear red flags table up front is genuinely helpful for distinguishing actual hangs from hitches or general slowness. With 173 installs and solid security audits, it's already seeing real use. If you're debugging unresponsive UI or trying to make sense of field hang reports, this cuts through the noise.
