  • They talk about Crunch

    Federico Viticci, MacStories – 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.
    Jacob Penderworth, Mac.AppStorm – 10/10. Extracting the contents of an iOS app can be confusing, but this app makes it effortless.
    Tim Van Damme, @2x – 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.
    • Requirements

      Crunch requires OS X 10.10 (Yosemite).

      If your Mac doesn’t meet the system requirements, you can download an older version (OS X 10.7+). Note that old software is unsupported.
