Exposure on dating apps is usually one-sided: you show everything, hope they are real, and find out later. Ohrny makes the reveal a decision two people take at the same time.
Inside a chat there is one card. Each of you taps "I'm ready" when you are. Nothing happens until both taps are in. Then photos, age and distance appear for both, in the same second.
Because the reveal is mutual, nobody is ahead. Nobody has your face while you have nothing but a handle.
