The Let's Date iPhone app connects to your Facebook account, but you also answer some additional questions about your interests that show up by your photo. Then, like with Tinder, you pick "Let's Date" or say "No Thanks" until there's a match. The main thing that sets this app apart from those with similar concepts is that there's a "wingman" feature that allows you to recommend dates to friends. You can even set up a wingman account if you're just interested in setting up your friends, not actually dating. If you've used the app, weigh in below!
