.APP file format is an application format for Mac OS X operating system. It is an archive file which contains the executable binary file along with the other resources that are required for proper execution of the application.
All these files are packaged into a single file known as APP file and therefore this file is executable and if user requires to install a specific application he has to execute APP file associated with it and the operating system runs the internal binaries included in the APP package. The file can be uninstalled using the same process. The APP file is used for Mac OS X only.

There can be more reasons which determine that you are not able to open the APP file (apart from the lack of the proper application installed).
First - the APP file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the APP file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the APP file should be solved.
Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the APP file has not been completed and it cannot be opened properly).
