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 ball tester you can check if your tennis balls still are playable.
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).

"The app is very, very impressive. I get more tension diagnostic questions than just about anybody in the universe, so this is a very good thing to be able to recommend."
