Crunch Tour

They talk about Crunch

Crunch does one thing very well, and I’m sure it can become an invaluable tool for anyone who designs and develops for iOS and wants to “know more” about apps and how they’re created, at least from a graphical standpoint.”

10/10. Extracting the contents of an iOS app can be confusing, but this app makes it effortless.”

A great way to learn how to design for mobile is by examining other apps. Even better is looking at the resource files and how they’ve been sliced.”

Frequently asked questions

Will my Mac run Crunch?

Crunch requires macOS 10.13 (macOS High Sierra). If your Mac doesn’t meet the system requirements, you can download an older version: OS X 10.7+, OS X 10.10+, OS X 10.11+. Note that old software is unsupported.

Is Crunch available on the Mac App Store?

The app is not available on the Mac App Store. Crunch is only offered on this website via FastSpring.

Why Crunch can’t find iOS applications from my iTunes library?

iTunes 12.7 published on September 12, 2017 and later versions remove the ability to download and manage iOS applications. Because of this change, it’s no longer possible for Crunch to get access to iOS application archives (.IPA files) downloaded using iTunes. Go to this support page to find some solutions, including the installation of a special version of iTunes, actually tagged as version 12.6.3, which gives the ability to download and manage iOS applications.

Is it possible to extract iOS applications found on my iOS device?

Crunch cannot connect to your device directly to upload iOS applications. This operation is not supported by the macOS SDK and the access to the file system of an iOS device is disallowed for security reasons.
