I enjoyed this app and paid the subscription as 5 errors per day were used too quick, especially when you are marked incorrect with the smallest of typos in a long sentence. Since then, I am getting more and more frustrated with it. The speaking exercises no longer work. It errors immediately without allowing any input. I get no response when emailing dev, or reporting issues in the app directly. You never receive feedback on anything, and some of the speakers are horrible to listen to.
