Men should avoid online dating apps because the dating apps will remove your most valuable asset: confidence with women. Online dating websites will make most men beggars with women because the ratio of men/women highly favors men. The non-personal nature can cause women to become flakey in choosing men.
As an experiment, a male friend and I created a woman's profile on a popular dating app. We wrote a well simple profile for a 20 year old, Caucasian woman, who was in college, working part-time in an office, and looking for a monogamous relationship. We answered every profile question, so the profile was a complete and used proper English. We had unique photographs of a pretty woman, who was about 5'6", slender build with B cup, long brunette hair. The website was free. The dating website's search engine showed there were about three times as many men as women on the website in the 18 to 30 age range.
The results blew our minds away. Less than 24 hours later, we had over 100 messages from men. We did not read or open all of the messages (it was overwhelming), but some were well thought out where the men invested time writing a detailed, customized response. The dating app allowed users to see if a user had logged on, if messages were opened or deleted. We never responded to any of the messages and did not delete any messages during the experiment. By day two, we received repeat messages from about ten of the men from day one, saying they noticed that we logged in and were following up. By day two we had over 200 messages from different men. The response was overwhelming - literally. We closed the account around day three, we felt bad for the guys.
Online dating has become a billion dollar a year industry. Online dating highly favors women because of the ratio of men to women; fewer women are comfortable meeting strangers on the internet. Online dating promises an endless supply of men, so many women do not respond and become overly picky. For instance, with online dating a women can limit matches to men who are only 6 foot tall or taller; that height requirement eliminated about 85% of the male population. Women can't do the same in person. 99% of women are shorter than 6 feet, so as long as your are taller than the woman, you are nearly as good as 6 foot tall in-person.
Below is the reverse experiment where an 18 year old woman tries being a man online dating and discovers how flakey women can be in responding.
My suggestion is to meet women in real life, the way our parents did it. Go shopping at WalMart or Target. Go to a shopping mall. Volunteer at an animal shelter. Go to a dog park. Circulate and meet women. Say hi.
