Tinder is not a good one to use at all if you want a girlfriend. It's basicallya hot or not app and can lead to hook-ups. There really are no good dating sites that are free. I'm not sure if there are good sites for teens, but it's not something I have looked for. Google dating sites for teens and see what comes up.

I live in a city of 2+ million. 0% success. It is a horrific platform for meeting people when your morals consist of honesty and respect. Unless you are vain.
