If users were continually paying for the app, paying for Yelp’s APIs would not be as much of an issue. And I wouldn’t feel as guilty about the app being discontinued since if the fees were charged on a monthly basis, they would just end at the same time the app ceased to exist instead of facing an expectation upon purchase of “forever access.” On the other hand, how would you charge a monthly fee for an app that people are only willing to spend less than $5 for upfront? There are apps that I like and would like to purchase, but paying e.g. 24 euros per year feels like too much. So I stick with the free version...
