Good format, poor quality AI
I was double billed because my card declined. Several emails before they told me I could cancel myself, but still waiting for my money back. I like the format of the app, but the AI is poor quality. Not much feedback given on how to improve pronunciation. There is no way to have the AI repeat the sentences. If you take too long to speak, it just goes ahead. If you get it wrong the "tutor" either says try again, without help, or doesn't let you try again.
