You were correct for about 2-4 years of the smart phone revolution though. I think we all became lazy and and replaced "application/program/software" with app since everyone knew/used app to describe everything on their phone. I began following that trend when I realized most desktop apps are just blown up smartphone apps and former shells of more useful older programs.
