God, using "app" for Mac applications is a really big pet peeve of mine. Idk why, the word itself just seems so dumb and too simplified. iOS like.
No offense, but this is a request to editors...please use the word "application" for all Mac programs/software. Leave "app" for use related with iOS.
Apple used to call all their Mac "apps" applications on their website and throughout the OS. References to the word "application(s)" is becoming more and more rare, instead "app(s)" is being used more and more often. Really annoying. It may sound weird to you, but it's a niggling pet peeve of mine.
