About eHarmony

eHarmony uses a comprehensive compatibility matching system based on 32 dimensions of personality and relationship science. New members complete a detailed questionnaire, and the algorithm surfaces highly compatible matches rather than a large pool of random profiles. This makes it slower-paced but more intentional than swipe apps. eHarmony is best suited for people who are serious about finding a lasting relationship and are willing to invest time in the process.

About Plenty of Fish

POF uses a chemistry predictor and relationship needs assessment to help match users. The site caters to a wide age range and is particularly popular in English-speaking countries. POF Premium adds profile highlights and extended search options.
