Online dating only works if you are aged 18 to 25. When you are in your 30s or 40s or older, dating apps are a waste of time because you are too old and real life is better than online.
I never had a smart phone and never bothered with dating apps or social media. With no barriers to make an account, no verification process, anyone can use fake profile and put up some fake photos to waste people's time. There are so many guys pretending to be women online. Women do not need to be online to attract a guy, they get heaps of approaches in real life. Online is a last resort and if you have any common sense as a guy you will not waste your time.
