Tennis Vibes allows you to measure the tension of your strings by detecting your stringbed vibration frequency.
You can install it and use it for free so just give it a try! After downloading it you can create your racket by inserting all the details or just insert the size of the racket and calibrate the app if the racket is freshly strung.
In the main page, choose the racket you've just created and press start. Hit the racket in order to produce a clean sound and do it for about 8-10 times (you can decide to close the measurement process at any time by just clicking on the animation again).
At the end of the measurement process, the tension will be displayed. You can repeat the process how many times you like to be sure you obtain consistent results.
If you like the app and decide to become Premium, you will be able to save the data and display them in a chart, to keep track of your tension loss and remove Ads.
Tennis Vibes is powered by TensorFlowJS, a powerful framework developed by Google used for machine learning purposes, to detect the frequency generated by your Racket!
