You got a binary file and don't know its contents. Or some software creates binary files where you have a specification but don't want to decode them manually.
Synalyze It! allows you to create a grammar for binary files interactively. Unlike in regular hex editors or viewers the files are interpreted automatically for you!
Synalyze It! costs $4.99, but some features are only available in the Pro version at $24.99
