Do not buy.

What the heck: since it requires three line of code to put in all other keys, it is an obvious way to angle for beginners and make them buy the pro version.
The pro version only has 4 keys.
Neither has any explanation of anything, or FAQs.
Being an optimist, I want to believe it was designed by a 12-year old.
