Great language learning app.
I give it 5 stars because Ive met a few people who have been very serious about language learning and we have stayed in touch, and i really value it. However, 90% of the users just want to casually chat over messages, but never want to engage in a voice conversation or actual language exchange. I also hear there is lots of harassment towards female users. I would really LOVE to see a computer application, or even a web-application to take the conversations to another device.
