Get Know App state?

I have an app that does some work every 180secs, while the process is
running i do set the app as "busy" and show icons and wait cursors on it.

Now, im doing another app and i need to query the state of the first to know
if its busy or not, what would be the best way to do that?

I have been thinking in add a function in the primary app to create and
delete a "busy" file and use it as a flag, but that option does not really
sound clean and professional to me... is there any other chances?
