I work with two recently divorced women and they are certainly having success with Tinder if you define it as dates. Which I guess means it’s working out for the guys they are hooking up with too. So the middle aged people seem to be doing ok. They do say there are guy-bots on there, scams aimed at women.
Both these ladies say they will talk with someone for a few days only then want to meet IRL otherwise won’t continue to engage; my husband said that was also his rule when using the dating apps. We met online but not through a traditional dating app and I wasn’t really looking for anything serious it just worked out that way. About 10 years together now.
About half of our grown children got long term boyfriends/girlfriends on the dating apps and half by luck in real life.
