You're right about apps being popular and continually growing in importance.
However, you're talking about a task (creating/updating a CV) that takes a lot of manual work and editing. It could certainly be automated to a large extent by grabbing existing information from LinkedIn or Facebook or wherever. But when you get down to the details, there's a lot to write. That will never be fun to do in an app.
I can't imagine people caring how "fun" a CV app/website is so long as it helps them get the resume updated and get a new job.
