A free program for iPhone, by Yusuke Mori.

Langmatch is a language exchange app that connects people who are interested in learning languages from each other.

If you are looking to improve your languages, expand your vocabulary, and learn new phrases, this app will be a helpful resource. 

Langmatch is a free app that allows users to easily swipe right on another user’s profile to indicate interest in a match. Users can also swipe left on another user’s profile to indicate that they are not interested in that user. Once you have matched with someone, you can start a chat with them.

You can also search for other users who speak the same language as you. This way, you will be able to find a partner who is interested in learning more about your language.
