stringster – für Tennis app for iPhone and iPad

Play tennis more effectively with fresh, lively strings!

Use "stringster for tennis" to analyze the condition and the tension (stringster PLUS) of your strings based on their sound.

WHAT YOU USE IT FOR:

- to monitor your string wear out over time
- to recognize the appropriate time to restring your racket
- to check your stringer’s performance

THE BENEFITS FOR YOU:

Playing your tennis racket with fresh, "lively" strings has decisive advantages:

- more feel for the ball and more controlled strokes
- higher repulsion power
- better shock absorption on ball impact reduces the "tennis elbow" risk

When the strings wear out, feel and control of the ball get lost. This will make your game more insecure. The fun of the game and the performance suffer.
