This app will NOT teach you how to fight with a sword. But if you're already being taught, this could help you practice. Basic sword strikes can be numbered one through eight. This app generates sets of random numbers and has the ability to call out the numbers. That way, you can follow along as the numbers are called out to practice your strikes. Simple, but useful.
You can change how many sets are generated and how many random numbers are in each set. You can choose 1 of 3 voices to call out the numbers. If you want you can even increase the wait time between the numbers called out or the sets.
