Features for introverts: The SmartPick can really be your best friend, serving as the best icebreaker. If both you and someone you're interested in both vote "yes" on each other's profiles, the SmartPick feature will let you know the good news by email and shoot you a message in your Zoosk inbox. Another good option is the Super Send feature, which could help eliminate the scary feeling from being the one to make the first move. Choose a message to break the ice, then allow Zoosk to blast it out for you using Super Send. If someone indicates they're interested by writing back, then you get to view each other's profiles.
One thing to note if you don't fall into the cis-hetero dating pool: While most of the apps reviewed here are inclusive, there are those that are friendlier to the LGBTQ community than others. For example, OkCupid goes beyond forcing users to choose between being a male or female, including options like Hijra, genderfluid, and two-spirit. If you're a man seeking a man or a woman seeking a woman, you'll want to steer clear of eharmony: It doesn't even give you the option of a same-sex match.
