Shadow Box is an application that shouts out random boxing combinations.

There are four settings Training, Easy, Medium, and Hard.
The Training setting will shout out all the basic strikes and some combinations. Only 100 strikes/combinations will be commanded.
Easy will only yell 100 easy combinations at random.
Medium inherits all easy combinations and adds new combinations. There's only 200 combinations at this setting.
Hard inherits all easy and medium combinations. There's new combinations added with significantly higher complexity. At this setting there's a total of 300 combinations.

All of the combinations can be switched to southpaw at the home screen. The southpaw combinations mirror the default orthodox setting.
