Okcupid.com: I used OkCupid several times in the past and have never had success with it. It is 100% free to use and 100% low quality in my view. I can’t tell you how many messages I sent as a member of this site without getting a single response. Nevertheless, it has a massive membership base and I have friends who give it much praise (maybe they have the magic touch), so it is worth adding to your dating site list as a last resort.
Tinder is a location-based application that filters the matches according to the location of the user; users are able to choose the maximum distance they want to focus their search on. They are also able to filter down matches by age and gender. Tinder is known for its unique swiping feature. If user's find a potential match, users swipe right. If user's do not like the candidate, users swipe left. Tinder is used more as a dating application in many college campuses.
Changes in the last year have made OkCupid a bit more like Tinder, focusing more on swiping and eliminating the ability to message a user without matching with them first. You can still send a message -- it just won't show up in the recipient's inbox unless you match. Because who doesn't enjoy sending a thoughtful message to someone who might never see it? However, OkCupid has pointed out that these changes did help lower the number of offensive messages users received, which might be a worthwhile trade-off.
This app wants to find you more than just a one-night stand or a cool-for-the-summer situation. That said, you're going to have to work for it. To join, you have to fill out an extensive survey, and you can't see photos of your potential matches unless you pay to subscribe. If you're out to spend more time finding your mate, eharmony is a good (if more costly) option. That is, as long as you're not looking for a same-sex mate: That's not an option here.
