eHarmony has established itself as a pioneer in the online dating space, differentiating itself through its comprehensive compatibility matching system. Founded in 2000, the platform uses a detailed questionnaire to match users based on psychological compatibility rather than superficial swiping. This approach tends to attract users seeking serious, long-term relationships rather than casual dating. The platform boasts impressive success rates for marriages and committed relationships. However, the extensive sign-up process can feel lengthy, and premium memberships are pricier than competitors. The user base skews slightly older and more relationship-focused, which is either a pro or con depending on your goals. For those genuinely seeking meaningful connections and willing to invest time in the process, eHarmony remains a solid choice.
