RacquetTune - String Tension App Details

Listen to your racquet and perfect your game! RacquetTune ensures that your racquet is ideally suited to your style of play. Simple and straightforward to use, the app uses the sound generated by tapping the strings to calculate the tension with high accuracy. In addition, the interactive swingweight calculator aids in customizing your racquet to fit your own stroke pattern, while the stiffness calculator allows you to simulate different racquet configurations. RacquetTune not only makes it easier to decide when it is time to restring, it is also an invaluable tool when testing different racquets and strings and in identifying which of your racquets is best suited for different types of games. RacquetTune also allows you to check whether your stringer is consistent in his work. RacquetTune includes the following user-friendly tools: Tension measurement - Quickly determines the tension and stringbed stiffness. - Able to detect changes in tension as small as 0.1 kg/0.2 lb. - An accuracy indicator ensures results are consistent. - Graphical presentation of sound waves helps you find the ideal way of tapping the strings. - Settings can be customized to serve tennis, squash, racquetball and badminton racquets, respectively. - View the tension history for each racquet as a list or a graph. - Email a spreadsheet with test data. Swingweight calculator - Add as many weights as you wish to the frame. - Move and change weights to visualize how swingweight, balance and sweet spot location are affected. - Enter target values for the racquet and let RacquetTune distribute the weights automatically. Stiffness calculator - Simulate various racquet and string configurations - Vary tension, string type and racquet head size. - Shows load-displacement curves, stiffness and elastic energies - Handles the large deformations encountered in actual play View a demo video at racquettune.com RacquetTune has been featured in tennis magazines in USA, Italy, France, Germany, Sweden and Norway. "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." Jonathan Wolfe US Racquet Stringers Association Note, that the actual string tension in the racquet and the setting seen on a stringing machine are two different things and therefore incomparable - more information can be found at racquettune.com.

  • Best Thing so Far

    By Switch God
    To date there is not an accurate device to measure string tension once the frame is off the machine. This app is closest thing to a real solution. Based on good science this will give excellent data on RELATIVE tension. Meaning you can now track tension loss over time as well as compare the sticks in your bag before you step on the court. The one caveat is that it does not come close to calculating absolute tension. I obtained wildly different tension numbers compared to "at time of stringing" tension. As much as 10-15 pounds off. But for measuring changes over time this app is the best thing out there!
  • Essential

    By kung-fu panda
    I have 3 kids who play competitive tennis and so stringing has become essential. I find the app to be incredibly accurate, allowing me to get predictable tension every time. I could calibrate the tension on my stringer with the reported tension on the app but that's not necessary since the readings are so consistent. I now have something like 10 different racquets and at least that many strings in the database . It's easy to add more. It's great for checking tension after a couple of uses as well as for actual stringing. Very impressed. I've strung over 100 times using it and I'm very satisfied.
  • Very clever - and good

    By msharkm
    Great way to track the loss of tension of your string job. 1st version it was sometimes tough to hit the and get a reading; with the current version it almost always gives a good reading.
  • Works great for me

    By Obieseven
    Great little app. I have three racquets that I have strung the same (50lb) on a digital machine with full bed poly every two to three months. I check the tension with the app every three to four weeks and can see the steady decrease to about 40 lb at which point I restring. I play with confidence that nothing wacky has happened to the tension.
  • Perfect for recreational players

    By Doc6284
    Awesome app. Great instructions on how to use its functions and the information it provides is easy to read.
  • Does not work as described

    By SMA 3.5 player
    Strung Babolat PD 107 today at 54 reads 41.3 lbs. TiS2 strung yesterday at 55 today reads 49. Not happy.
  • Teaching pro

    By Jimmyoldboy
    Very useful in tracking relative tension loss over time or comparing tension in multiple rackets. Helpful in showing members when it's time to restring.
  • Does not function well

    By Boombostic
    This app says one of my racquet is 23 psi. It also says another racquet is 54 when I know it is 60 psi. All of the shock absorbers are off of the racquets. Mind you this is after plucking the string 99 times.
  • Outstanding!

    Outstanding App!!!
  • Works well not perfect but good enough

    By Lolygagv2
    I believe the string tension is accurate to a certain degree. This degree is good enough for most stringing applications and you usually get within a few pounds of what is accurate especially useful if you have multiple rackets, you string together and you want to know where the tensions are on each of them relatively
