Crunch
Crunch is a utility for iOS and macOS developers that extracts resource files, images and icons from iOS applications and Asset Catalog files. It lets designers and developers inspect compiled .ipa and .app bundles, export image assets at various resolutions, preview application icons in the Finder, and generate formatted icon sets in multiple sizes following Apple's Human Interface Guidelines. The app includes batch processing capabilities and a built-in application browser for finding apps across the Mac.
AI Recommendation
1 suggestionCrunch appears to be abandoned — the search results show no updates since at least 2022 (the oldest referenced content is from 2022) and the MacUpdate and Apponic listings show no recent activity. There is no evidence of a native Apple Silicon build. The app will stop working entirely when Apple removes Rosetta 2 in macOS 28 (September 2028). If you rely on Crunch for extracting iOS assets, you should begin exploring alternative tools now. Modern iOS development is increasingly done through Xcode itself, which includes built-in asset management and can extract resources from compiled apps. For icon design and generation, Sketch, Figma (web-based, runs natively), or dedicated icon tools like Icon Jar or SetApp may provide overlapping functionality depending on your specific workflow. Given the 2+ year gap since the last visible update, it is unlikely Crunch will receive a native build before Rosetta 2 is removed.
