Setting up your profile involves a rather in-depth chemistry assessment of more than 70 questions. This means you'll have to think a little bit about your own personality, how others perceive you and what you want in a mate. Questions include whether you consider yourself productive and whether you're seen as stubborn. You answer on a scale, which is nice because it means your answers can be more nuanced than yes or no. There are several other questionnaires available to continue to flesh out your profile, but they're not required. Messaging and viewing user profiles is all free on Plenty of Fish. While our reviewers don't think the website is very well designed, the free mobile app is also an option that's super easy to use. The one downside to any service with free messaging is that you could feel overwhelmed if you find yourself with a flooded inbox. On average, the three fake accounts we set up for testing got 40 matches in 24 hours, the second highest of any service we tested. Of those, 22 percent were "top prospects," which is the site's way of saying those users are highly compatible with you.
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.
