Tennis Serve - ProCoach is a free Android app designed to help tennis players improve their serve. Using advanced technologies such as Artificial Intelligence and Computer Vision, the app can analyze a video of your serve or your tennis partner's serve in just a few seconds. The app will then provide a list of possible issues with screenshots and short descriptions to help you identify areas that need improvement.

The app can identify several tennis serve issues, including body weight transferring backward, landing on two legs instead of the front leg, balance issues when landing, foot faults, insufficient elbow bend, elbow too high or too close at trophy position, and insufficient knee flexion. With the help of Tennis Serve - ProCoach, tennis players can get real-time feedback and improve their serve quickly and easily.
