This app is great
This app is great for increasing comfort and confidence in speaking a new language with no real pressure. There are several features in the free version that, as far as I can tell, make the paid version unnecessary. Based on what I see in the negative reviews of this app they are people who are unaware of the settings, don’t have the basics of their desired language enough to be conversational or nitpicking about the esthetics of the AI bots.
