Speaking as an 18 yo as I believe age matters most when you're talking about a specific online dating app

Used Tinder had about 300 matches; hot ones never responded, average ones would either admit that they are using the app for attention or would only want me for my dick. There were very few quality girls on there and the best ones I met through friends, not online dating.

Haven't touched the other dating apps as Tinder's the best for my age apparently but I deactivated it because dating is an absolute waste of time.
