If you're strictly looking for a hookup app, it's always best to prioritize your privacy, and Pure does just that. The free app, designed to facilitate casual flings, erases your profile every hour (although you can easily restore it if your heart desires). The app is basically a geo-location-based online personals app that allows you to list yourself to other local singles for 60-minute periods to see who you match up with. If you mutually match, you can strike up a quick chat with the matching user, but be sure to exchange contact information quickly, as you'll lose contact on the app with that user. After one hour, your profile “self-destructs,” erasing your short online personal listing so nothing traces back to you.
Zoosk recommends showing your natural smile, citing a 2015 study that found people are drawn to a genuine show of pearly whites. That same study found people prefer a photo if the subject is tilting their head slightly, and if you're a woman seeking a man, make sure to incorporate the color red somewhere in your photo. If you really can't decide which photo to choose, don't be afraid to ask for a little outside help. A 2017 study found people tend to pick out less favorable photos of themselves when compared to letting others choose, so go ahead and ask your friends to help you!
Another strong option if you're just on the hunt for no-strings-attached action is XMatch. As you'll clearly see if you visit the site, XMatch is all about giving you a taste of the "XXX action." With more than 75 million members, the hookup-centric site will serve up a ton of possible sex partners in your area, whether it's someone who shares your specific kinky desires, or other people also looking for no-strings attached sexy hookups.
Plenty of Fish (or POF) tries to combine the ease-of-use of a simpler matching service with some of the brains of a more robust, comprehensive dating site. It matches based on mutual likes, but the more information you add to your profile, the more intelligently it'll try to match you. It has a speed matching feature, called MeetMe, which will present you with singles in your area that match your interests quickly, so you can cut through the fluff and contact someone about a date. Alternatively, you can browse matches by interest or by people who live nearby. At the same time though, it retains some of the simplicity of other services—if two people like each other's profiles, you'll get a notification to connect right away. How much effort you put into finding a good match—whether you go by mutual likes and location only or you fill out your profile with tons of information—is entirely up to you. Oh, POF is also free, and offers mobile apps, just like the other services.
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.
