The Shot Stats Challenger is a unique device that aims to improve your tennis game. The compact device clips onto a tennis racket and tracks your swing metrics and other performance indicators.
The device uses an embedded accelerometer and gyroscope sensor to measure and store statistics. It measures how much time you spend on the court, the speed of the racket when it makes contact with the ball, the number and types of shots taken, the extent of spin on the ball, etc.
The Shot Stats Challenger includes a small, high-contrast touchscreen that allows you to view your stats. It can also export data via Bluetooth to smartphones and other smart devices, allowing you to peruse the data for in-depth analysis of your game.
The device can even be set to provide live audio alerts during play, letting you know when your game is off the mark and what you might be able to do to improve.
