This app is a solution to lack of tennis court access, or another player. Make use of this app and a small open ground to train yourself in Tennis Endurance through interval training meant to simulate a real match like environment. Apart from this you may also use it to focus purely on footwork across the multiple shots. The app has a variety of shots that should have you moving energetically all over, just like in a real game of tennis. It is a great way to build stamina and endurance for tennis matches.
