The Waving app doesn’t let you see what the people look like that you’re matched with. All you have to do is describe the kinds of dates you’re looking for, and the app will give you a selection of people they think would be a good fit. Then, all you do is stalk the people you might want to match with – by listening to recordings of their voice.
It sounds a bit crazy but a lot of people are jumping on board. Who knows. You might find "The One" this way.
