This indicates a dependency (on mobile devices) that is not inherent in the problem domain (following a page on Facebook). The dependency on mobile devices impedes the critical business function of receiving feedback from potential users. The app prototype could just as easily be a web page.
Overall, the app has a dependency on Facebook's API's and terms of service. Facebook can change theses arbitrarily or decide the app violates their intent.
