Our simple app has more than 11,000 users currently and so far everyone has given us rave reviews about the app. Given our huge user base, we're now considering monetizing it.
Of course, we aren't going to start charging users for the existing app. Instead we were thinking of building some of the frequently requested features into a paid version. Is this a good idea? If you are a user, would you like the fact we are charging for the features you requested?
