racquetTune - String Tension
With racquetTune you will always have the optimal racquet to play with. Tap the strings and racquetTune will use the sound to calculate the tension with high accuracy. The interactive swingweight calculator helps you customizing your racquet. And with the stiffness calculator you can simulate different racquet configurations.
You can check when it is time to restring or which one of your racquets that is best suited for different types of games. It is an invaluable tool when testing different racquets and strings. racquetTune also allows you to check whether your stringer does his job consistently. (Note that the actual tension in a racquet and the setting on a string machine are NOT the same thing).
