Most businesses don't really need an app and trying to develop one is a waste of time and resources on a fad. You seem to have a vested interest in making that claim, but I think that claim is really exaggerated. Some businesses who have a lot of clients and provide a specific type of service that's compatible with that might need an app, but most don't. For instance why would somebody selling backlinks or content here need an app? It's only an obstacle they could put in for their clients who would need to install things and so on while a responsive website would be more than adequate and easier to use for everybody involved. Not everything needs to be an app.
