Good concept but very poor functionality – Lext Talk - Language Exchange! Review

This app is very basic. The concept is great however, in that it lets you find people who are learning a language on a map. In the 5 months I've had it, it has been updated just once, and that was to include an option to send pictures. The interface pretty colourful and basic. The chat rooms are not monitored so there are spam and random conversations. I really like the idea of the map that shows where the users are but this app itself is not good. After three months since Iast used it, when I message a person, it says there is an error. This error doesn't happen for every chat conversation I have.
