Let the iPhone listen to your Tennis Racquet

in Sports (E)

[prMac.com] Stockholm, Sweden - racquetTune is a cool and innovative tool that let tennis- and squashplayers check whether their racquets are correctly strung. A couple of taps on the strings, and racquetTune analyzes the sound of the racquet and displays the tension with high accuracy.

Additional functions like a swingweight calculator for customizing racquets, makes racquetTune a serious tool that even the professionals praise: "It is well made, works amazingly well, is child's play to use and is always with me and ready to use" says John Elliot, professional racquet stringer in Paris.

"The motivation behind racquetTune is to give tennis players everywhere an easy to use tool to check when its time to restring their racket, or to find the optimal tension to play with" says Sten Kaiser developer of racquetTune.

racquetTune uses the sound to determine the frequency of the strings. The frequency is then converted to the tension of the strings. The accuracy is indicated on the display and can be improved by tapping the racquet several times.

To evaluate racquetTune a series of different racquets were tested at the Royal Institute of Technology in Stockholm. The stiffness of the strings was compared with the results from racquetTune. A very good agreement between the two was found for a wide range of racquet- and stringtypes.
