Totally unusable
Revised review it’s stopped working and says something has gone wrong which has been reported to their engineers, this has been going on for over a week and the app is now totally useless, so my original review below now longer applies other than to say it hadn’t improved on my comments. I really like the app, the interactions are good. However it’s twice restarted the lessons at the beginning and I can’t see how to go back to the level I should be on which is frustrating. Also when giving answers the app doesn’t always give adequate time for you to speak and can mishear your reply when it is actually correct.
