From time to time I have mentioned an App for checking and tracking your racquet’s string tension.
RacquetTune is a string tension testing App available for IOS devices on iTunes, the App Store. Last I checked, it cost $1.99. You’ll find a link in our Tennis Links section at the top of the MWSaHTB Blog.
All players, not just racquet stringers, may benefit from the use of the empirical data provided with this App and your iPhone/iPad. Over time you may be assisted in determining when to restring or cut out that poly before developing tennis elbow.
Finally, I have no affiliation with the software author/vendor and no warranty is implied.
