macOS, is my app active?

[Bob Sneidar]

on mouseUp
   put "tell application " & quote & "System Events" & quote & cr after tApplescript
   put "set activeApp to name of first application process whose frontmost is true" & cr after tApplescript
   put "return activeApp" & cr after tApplescript
   put "end tell" & cr after tApplescript
   do tAppleScript as appleScript
   put the result
end mouseUp

works for me
