That logic only applies if you think of an app as an end-in-itself, as the final product to generate revenue. While that may be a viable business model in some cases, I think it misses the true opportunities for making money with a mobile app. In my experience, apps work best as a gateway to another revenue stream or as an add-on product to an existing service. I only use free apps but I have subscribed (and paid) for web sites associated with those apps for expanded services. A good example is an exercise tracking app which records your exercise routines, maps routes, etc. If this app is free but uploads your data to a web site which provides expanded functionality, online communities, and other services, I'd gladly pay for an account on the site.
