Number of shots

• Total number of shots so far in the current session.
• Drop shots or a short rally with small swings might not be judged as shots.
• A longer follow-through is easier for your shot to be detected.

Swing type

• Your swing type when you hit the ball.
• Swings are categorized as Settings, Slice Forehand, Topspin Backhand, Slice Backhand, Volley Forehand, Volley Backhand, Smash, and Serve.
• Similar swing types such as slice and volley or serve and smash may not be categorized as expected.
• Overhead serves are detected as serves, but underhand serves are not.

^(*1)Hitting the ball and swinging the racket through makes it easier for the app to detect the swing as a slice. Also, hitting the ball and not swinging the racket through (stop) makes it easier for the app to detect the swing as a volley.

^(*2)If you want to increase the chances that your serves are detected as serves, move your racket as if you are hitting the ball overhead just before serving.

Impact spot

• Displays a visual indication of where the ball impacted the racket's string bed.

^(*3)The app cannot generate correct data if frame shots are performed.

• There are 10 levels of spin for both "+" and "-".
