What is app file? How to open app files?
File type specification:
The .app file extension is related to the Psion OVAL.
It is a rapid development environment for hand helds - quick, cost-effective programming.
One of the great things about the Psion computers is how easily they can be programmed.
This can be done on the Psion machine itself (using the built-in OPL editor) or by using a PC-based software development kit (SDK), software development environment (SDE) or Psion 'emulator'.
