This app TennisCoach assists individuals in improving their tennis skill [1]. In communities with low incomes, it is difficult for players to find affordable classes and courts to play on. With prices of coaches and lessons rising higher and higher nowadays, it is extremely difficult to improve for people who cannot afford them. Our app provides an easily accessible way for people to improve their tennis skills. It allows the user to upload two videos: one of themselves, and one of a professional demonstrating the same move. This app has a visual representation of the mistakes of the player, a side-by-side comparison of the player’s and the professional’s stroke, and a detailed breakdown of the player’s movements. The video processing part is through pose estimation and K-means algorithm [2]. Users can review previously uploaded videos on the history page. Users’ data are safely stored in Firebase guarded by Firebase Authentication. With our app, tennis will become more available for players from many different backgrounds.
