Useless as nobody uses the app. Those few exceptions will definitely ghost you after like two messages. The app will try to push you to subscribe as even checking who liked your profile is unavailable if you don't. Sending messages is only available if you have a "super like" match. Super likes are also not free. Overall it's just a waste of time, the subscription is overpriced (as in return you will still get nothing), I don't recommend at all.
