Very Intuitive to use
I bought this app to teach my children to type properly. At first, we did not understand how to progress past Lesson 1. It was very frustrating as it seemed all the menu options are disabled (even when the Stop button had been pressed). Online support is just email, but the response from developer came within 36 hours, and wuickly cleared up our confusion. The Help topics seem a bit sparse, but if one reads carefully, there is a good chance the answer to your question will be there. The application is very intuitive to use.
One annoying issue is that the app monitors your keyboard input and makes noise and thinks yourer typing in it even when its in the background. I find this annoying as I often have need to switch to other apps as I work, and I find this behavior to be distracting. It forces me to quit the app when moving to another task instead of just putting it in the background.
