Great app for keeping track of tension loss!

If you wait till your strings break to restring your racquet, you are waiting too long! Strings lose their ability to transfer energy to the ball and create the spin needed for accurate powerful shots. This app helps me keep track of my players string tension loss and replace the strings before they lose playability. I highly recommend this app!
