Tinder optimises for volume and speed: fast swipes, fast matches, a wide funnel. It has added AI-assisted matching called Chemistry in some markets, plus events and group features. That design suits you if you want to meet many people quickly.
BiggDate optimises for fit. Onboarding takes about 20 minutes, matches are capped at 5 a day, and contact starts with a Soul Knock question. The funnel is narrow on purpose, for people who've found that volume isn't their bottleneck — fit is.
Neither is wrong. Different seasons of life call for different tools.
