I say this as a paid user - don't alienate your free tier users by removing more and more functionality. What makes an app like Grindr worth using is having a lot of other users to interact with. It seems you're putting more and more functionality behind a paywall. Many users can't or won't pay for the service, and if it becomes "unusable" to them, they'll stop using it entirely. They'll go elsewhere. And then, with fewer people on the service, it won't be worth it to the rest of us to keep paying for it, so we'll leave too.

Want proof? Look at Manhunt. Back around 2006 or so they were the top gay site for meeting people, but they moved more and more behind the paywall. People left. You know where they went? Grindr! Don't repeat their mistakes. There's plenty of alternatives out there, don't let one claim your throne.
