Online dating apps are virtual internet places where people can easily meet peoples online and nearby them without visiting the person in real. But only problem is that these apps are dominated by certain gender groups (generally males) and this imbalance creates problem for minor gender groups (generally females) because they (females) have so many options to choose and have more options to negotiate hence creating very unsustainable matching environment (this means not suitable match) because if men or women (because of crowd women get a lot of matches which does not attractive for them due to so many interest from male ) will end up undated then they will flew from the apps and whole system will be in trouble.
This problem was solved by some economists by restricting no of right swipes or making the app paid for every swipes- known as artificial scarcity.If people will have less options then they at least look at the complete profile of the person and then that can be a serious relationship finding model and other person will also take it as a serious.
