I use the couchsurfing app all the time. It is how I made the large network (of English speaking) people that I have since moving abroad. I go to their weekly meetups, picnics, and other events as well meet people through the hangout when I'm bored. I've stayed with two hosts and meet up with other travelers and locals when I'm traveling as well as meet on a separate trip with one of those travelers. Recommend to anyone who wants to expand their horizons, meet interesting people, and become a global citizen.
