Make this a free service. Generate greater revenue by charging any government or law enforcement agency an appropriate fee for each and every record they request. They will gladly pay, this is a common expense for any entity executing that sort of operation. And they will pay even if it seems exorbitant. If you still want to include ads, make them only show when the app is first opened or in very small and unobtrusive ways.

Grindr doesn’t need to be so feature-laden, nor does it need to be political. It can just be free and work well and simply. AND it can still be profitable.
