It asks me for my level; I'm half way through this audiobook (https://www.amazon.co.uk/Next-Steps-Spanish-Paul-Noble/dp/B0...), and have listened to the book before it a number of times, so I'd say I'm between beginner and intermediate. I think you could do better than a "what level are you, pick from 3 options" and throw you straight into a chat - ask some basic Spanish questions, and then try and figure out where the user is from there.
Next I chose Blanca from Barcelona, and she said an awful lot of words and I understood very little of them, so I think I'm not ready. Half the grammar lessons have both a Spanish and English explanation, and half don't.
I'll keep the feedback coming, but I'm on a train now and the questionable internet is not good enough for an actual conversation.
