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.

The site has profile verification options to ensure you are matching with real people and not fake profiles. On top of that, the site has a Smart Match system that essentially allows it to learn your preferences the more you use it, and the option to send a “Mega Flirt” that reaches dozens of inboxes every 15 minutes. It's a site you won't easily grow bored of that aims to help you become a better dater. best dating app
