It's a great concept, and I love being able to have a free form conversation in Spanish whenever I want. However, im finding the speech recognition to be extremely buggy. I often have to repeat myself and it leaves out words that I say or misunderstands me entirely. I'd use it way more if there were fewer issues. It's getting frustrating to deal with.

I did the free trial in French, Japanese and Korean. It was so fun! Some voices sound more natural than others. When you speak with the AI, sometimes I would just cough and it would write down something I never said. But that's a minor flaw to me and speaking is the best part about this app. I choose to have it correct me every time and I loved it so much! The drills, shadowing, flashcards and translation featues are really helpful. I think I might buy...

worst app possible, nothing uploads like at all every single second gives me a no connection message, even tho the internet is fine and all the other apps work normally, and i can't call anyone like at all, it doesn't even let me create an account.
