Shenzhen for viewing Mobile Provision Information

Highly recommend this open source program for MACs to disply the embedded .mobileprovision Information in IPA files:

This allows you to look at how an ipa file was signed and when it expires without having to unpack the file.
 
It’s easy to install from a command line:
 

        sudo gem install shenzhen

 
Then you can run a command like this:
 

        ipa info MYAPP.ipa 

Example Result:
