problem: tinder/etc are not healthy social mechanisms (details long, skipping). they have some value and this is exploited with smart business models (supported by covid, with social/basic instincts allure, etc…). it could be done better and open future options, with great monetization along the way.
solution: try to mix back some real world, old school, organic element to dating in the twenty first century (digital is unavoidable, but keep some grounding). use tags that are (optionally) visible in the real world. with RFID that can be disabled, and QR code as alternative.
you see someone with the tag. say hi. chat in person, tag or not for later review (to match or not).
