Any date finding apps on facebook?

[[N9] Dude [N9]]

Any apps for singles who r looking for a date/relationship, like date finder, on facebook? Preferably the ones which search for singles in the same city u live in.
Thanks. But it has got several drawbacks not being a premium user, for which u have to pay. I'll mark ur answer as the best answer If I manage to get any partner, else, this question is open for more answers. Thank you for responding.
