They weren't Tinder sized. They were only published in latam. The first (Mil Besos) flopped and my second attempt (MiAmor) got to a several hundred thousand downloads and I sold it for not very much because I was tired of the moderation. Neither exists anymore. This was more than 10 years ago. There used to be A LOT of dating apps around 2014-2018, I mean hundreds of them on the Apple and Play Store. There has been a lot of consolidation because almost the only thing that matters for dating apps is giving users optionality, which means having more user profiles the other ones.

I'm not claiming I'm an expert, but just sharing personal insight. It doesn't take many users before statistical observations of behavior make themselves apparent. Start producing 5-10k matches per day on your platform and you will see what people want and don't want really quickly.

I don't wish to belittle you but, if I were you I would certainly not be in this discussion saying things like "Source: I used to build and run dating apps" (you said this in another comment in this discussion) when making claims about the major dating app companies if these were the two apps in question.

Certainly not in the manner you conveyed your experience. The market dynamics and design problems of these apps are very well known. Given the scale of your experience, I would suggest your invocation of it as some kind of authority was superfluous at best.

Congratulations on your sale though. Have a nice day.
