Been researching this longer than I care to admit. Community input is worth more here than anything I'd find on a review site.
Faith-based dating platforms vary enormously in how seriously they screen for actual shared values versus just checking a box. The difference between platforms that genuinely serve believing communities and those that use faith as a marketing hook is significant, and you really can't tell from the marketing alone.
Christian Mingle and eHarmony's faith filters have the largest active user bases for serious Christian dating.
Would really value hearing from people with genuine experience rather than just what the platforms claim about themselves.
