Can an add-on for a browser, a plugin for a text processing (like Word) or a content unit for a software (like an Anki deck) be called an app without misunderstanding?
The definition of an app is a self-contained program or piece of software designed to fulfill a particular purpose; an application, especially as downloaded by a user to a mobile device (Oxford). So according to this definition, as long as the piece of software is designed to fulfill a particular purpose, then it is an app, right? Am I considered to be misleading if I mention them as an app? And does writing this kind of "app" make you a programmer, or developer?
I think they are big words, and I don't want to misleading people, but I need to explain to non-geeks know what I am doing.
