Purchasers may apply their Groupon toward membership packages granting access to Chemistry.com's online dating community, which is populated by hundreds of thousands of other singles. In addition to generating matches for each user, the site's tools help searchers create an intriguing profile, upload pictures, check your progress, and even decide on a fun icebreaking activity for the first meeting.
Chemistry.com, an offshoot of Match.com, literally coaches users through the nuances of online dating—its patented feedback system of personalized suggestions helps users avoid faux pas. The website's matching algorithm is as good as its feedback, too. Developed by anthropologist Dr. Helen Fisher, Chemistry.com's personality test informs each match percentage, as do the user's personal preferences.
