I disagree with you. Datting apps are tools. Dating apps have an algorythm that determines who shows up to you and to whom you show up. They also create a "frame" for interaction that favours certain behaviours over others.

For example, since many people decide to swipe by looking a picture without reading the whole profile, that means that looks are favoured over personality by desing. UNLESS, the person who upload the profile picture manages to show something about themselves with that picture. And it is not about being expresive, but about communicating with a single image (that can be photoshoped or very old).

It is said that "men are more visual". I don't know if it is really true, but might explain why we have this desing. Theoretically, someone could create an app that showed a "quote" so you so you decide over personality, but seems unlikely (less markeatable).

But I digress, what you need to use dating apps sucessfully is to understand the algorythm and play it to your advantage. I did, I met my boyfriend in one. Took me a few tries to "gamify" the system. And I can assure you it has nothing to do with social skills, but a lot about understanding "game theory".
