We spent five days trying out 10 different online dating services to figure out which one is the most effective and affordable. After monitoring three fake profiles for 24 hours, collecting match data and using the features of every website and app, our reviewers decided OkCupid is the best overall service. The free app is also easy to use, and our tests resulted in the most matches of any site we tested. We also spoke to several insightful people, including dating experts and typical users, to get a clear view of the modern dating landscape. This is becoming easier and easier with social media.
