I downloaded this app to talk with native speakers of the languages Im learning. so far, everyone Ive talked to on this app has been really polite and respectful, and I havent gotten any weird or creepy messages like you do on any other app that involves talking with strangers :) you go through an application-type process when you join, which involves a little waiting but is generally pretty quick and cuts down on spam, which I thought was pretty cool. my only complaint would be that sometimes the interface is awkward to use, for instance, I havent figured out how to use the filter for searching properly yet. really good app overall though!
