Okay, I'll give it a try. Is HelloTalk like a social media app? How do you connect with people on it?
The way I connected was by commenting on posts on the main feed by Koreans who wanted their English corrected. Easy for me as a former proofreader and editor. Doing this people offer personal thanks and you end up connecting that way. I also posted pictures of my Hangul writing practice sheets for comment on the main feed, the feedback I received was very helpful and helped me make more connections.
I also joined English practice speaking rooms for Koreans so they could improve their listening and speaking skills. Again, this helps with making connections.
Even though my Korean is relatively non-existent (I now have a 100-word vocabulary), I found study partners within a week.
Like most things, you get back what you give out.
