I find it good to make the distinction between "useful, functional application" and "limited, useless app".

When I hear "application" I think of Wireshark or Microsoft Word or Firefox - something big that does something I need it to do properly.

When I hear "app" I think "time-wasting utility" or "a different view of a website that is just for phone-users".
