I've been using 321 teen chat as a teenager for a few years but now I'm enjoying using the adult chat room on 321chat (and will probably end up in the senior chat room lol). It's free and very user friendly but the best part is the community itself. You do make real friends and it's a great way to pass the time in the evening. It works on mobile and desktop pretty much the same but I prefer chilling here on my laptop in the evening times. :)
