Pros:

Language is one of the most important things, because from language we can start a communication. Different countries must be different languages. Maybe this is the origin of the HelloTalk application.

With excellent apps for learning the language directly with people using the language, Chatbot is even available to train our language teaching. WOW

Simple application that has special function

Cons:

Since this is the first application in the world, there must be things to be fixed in terms of the system or whatever. But I believe it will be a cool app.
