1. My advice, download and use the free version but do not buy the upgrade.I bought the app but when I changed phones I only have access to the first five lessons.
2. Tried to contact the company and they won't respond.Great app! More lessons and a big review lesson with all learned characters would be amazing.
3. Nothing worse than a teaching app which immediately drains your enthusiasm for a new subject.I bought this app previously but had to buy it again when I got a new phone - a Moto5.
4. I just bought the upgrade, again! Somehow, I can buy and pay for an upgrade but I cannot submit a bug report and get a fix.
5. Clicking on Lesson 1 gives you a choice of tests, before anything has been taught.
6. Drawing lines in other apps on the same tablet is not a problem.
7. Trying to draw lines is frustrating and badly implemented.
8. This app used to work great on my tablet.
9. Also writing of characters doesn't work properly sometimes.
10. Now I can only take one test, after which the audio stops working.
