CMM is the Capability Maturity Model. It is not an application, but, rather, as you suggest, a type of status. More specifically, it is a "level of status" relative to the idea of how mature organizations tend to do things in terms of process. Also note that there are various CMM types. Check out the SEI site for specific details.
Have you read those documents at the site link I provided? They explain all of this. In short, yes, there are five levels to the basic CMM concept and these are related to what is called "organizational maturity", which does not speak to a specific application. If your friend is saying his "application level is 3" I am not sure what that means unless he is saying that his application was developed via a process in the organization that is rated at CMM Level 3.

It really isn't an application level or thing. It is a process measurement that is applied to organizations.
Level 1 - No process or very new process.
Level 2 - Some process are repeatable or tracking of items is in place.
Level 3 - Most process are repeatable and tracking of requests / defects is in place
Level 4 - All prcess are repeatable have an established development process that has worked for several iterations.
Level 5 - Every thing is done by a specification established by the company and is written down.
These may not be accurate, but I believe they are close.
