I can read and write and speak on an intermediate level but I have a hard time with comprehension when people speak to me. I heard about the Hello Talk App that connects you with native speakers that you can talk with. Anyone can give me the pros and cons of this App?

It's well worth checking out. There aren't really any cons. It doesn't cost anything and there are a lot of Thais wanting to exchange for English. Best thing is to just join and give it a try. Initial contact is by messaging on the app, but you can always arrange to speak to them after you've exchanged a few messages. I think it has built-in video-calling or you can exchange Skype or Line ids.

Thank you! I'll give it a try!
