app - Free On-line Dictionary of Computing (26 May 2007) :

  application program
  app
  application software
  applications software
  
     <programming, operating system> (Or "application", "app") A
     complete, self-contained program that performs a specific
     function directly for the user.  This is in contrast to
     system software such as the operating system kernel,
     server processes, libraries which exists to support
     application programs and utility programs.
  
     Editors for various kinds of documents, spreadsheets, and
     text formatters are common examples of applications.  Network
     applications include clients such as those for FTP,
     electronic mail, telnet and WWW.
  
     The term is used fairly loosely, for instance, some might say
     that a client and server together form a distributed
     application, others might argue that editors and compilers
     were not applications but utility programs for building
     applications.
  
     One distinction between an application program and the
     operating system is that applications always run in user mode
      (or "non-privileged mode"), while operating systems and
     related utilities may run in supervisor mode (or "privileged
     mode").
  
     The term may also be used to distinguish programs which
     communicate via a graphical user interface from those which
     are executed from the command line.

app - Jargon File (4.4.4, 14 Aug 2003) :

  app
   /ap/, n.
  
     Short for `application program', as opposed to a systems program.
  Apps
     are what systems vendors are forever chasing developers to create for
     their environments so they can sell more boxes. Hackers tend not to
     think of the things they themselves run as apps; thus, in hacker
     parlance the term excludes compilers, program editors, games, and
     messaging systems, though a user would consider all those to be apps.
     (Broadly, an app is often a self-contained environment for performing
     some well-defined task such as `word processing'; hackers tend to
     prefer more general-purpose tools.) See killer app; oppose tool,
     operating system.
