When it comes down to actually putting yourself out there and creating a profile, all apps ask for the basics: name, age, location, a photo, a short blurb about yourself, and (usually) if you can stand a person who smokes. Beyond that, it can be a bit of a crapshoot. Some apps, like Tinder, value photos over personality. Others, like eharmony, make you fill out an endless questionnaire before you can even think about browsing for your match. Still, Zoosk and other, similar apps ask so little that you're left to wonder what's being used to actually match you with like-minded love-seekers.
If you don't fall into the cis-hetero dating pool, you'll be happy to know that most of the apps reviewed here are inclusive. Even eharmony now finally allows for same-gender couples. However, some 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. Other apps target identities beyond gender and sexuality. For example, Kippo's nerd-friendly features attracts gamers, Vinylly connects matches people through shared love of music, and SilverSingles reskins EliteSingles for a senior audience.
There are a lot of resources that can be attributed to online dating and communication, click for more info. All you have to do is figure out which relationship format suits you best. The fact is that there are both classic options and options for those who are looking for only sex. It is up to you to decide where your profile will be.
