Oh, and if you think you're using it for free, think again. They are collecting all kinds of personal information about you
Also on the data collection front, the business model is more based around advertising, and just knowing you're single is all the info they need. They can bombard you with ads for events to go to, clothes to wear, etc. You're the most lucrative market if you're 18-35 and single.
Dating apps sell you on showing you more people you otherwise would never meet. The chemistry and "good match" are left to the two people to figure out via chatting and a date.
Dear God why would you do this to someone?
I'll tell you why: Why be content only meeting the subset of women I can meet face-to-face in my free time when I can complement my social life with a dating app that helps me meet more?
I can do both.
I can only understand your confusion if you have zero success on dating apps and assume nobody else has any success, either. And there are people obviously having success on dating apps.
Show me the data that says meeting many more potential partners leads to happier more fulfilling relationships, because I certainly haven't seen it.
If that is not the case I agree with you.
