Regarding dating apps and your lack of success: you have to understand that there is great difference in the numbers of male and female users in these apps. In apps like Tinder there are far more men than women, and they are far more needy. The reason you don't see success is because women choose other men instead of you.
On these apps, your looks and your photos are the most important element of your profile. Women have thousands of options to choose from, especially if they live in big cities, and often don't even bother to look at your description/bio. However, in many cases, particularly in smaller cities, they often do read it so write a smart one that demonstrates the good aspects of your personality, your interests, and that you have a sense of humour. When I was using the app, I would often be told that I had a very funny or interesting bio.
