The idea to use a smartphone app to determine racquet stringbed tension is not new.
The latest newbie is Stringster.
After downloading the app which is free, you must register before using it. Then you need to define your racquet and string make/model to the app before proceeding to test your racquet's tension.
Since the library of predefined racquets and strings are limited, I picked a string which has the closest characteristics to the product I was using - results as below. Must admit it is pretty good as my racquet which was strung at 23lbs with Gosen G-Tone5.
One good news is that if you do know the characteristics of your racquet and the strings, you can then use what's available in the predefined library (provided you have knowledge of the product characteristics) to provide a rough gauge of your racquet stringbed tension. The other is 1st racquet defined to your profile is FOC. After that you need to pay for the extra features.
CON is the predefined library of racquet(s) and string(s) does not include other major manufacturers such as Gosen, APACS, Fleet, Mizuno, etc. Hence accuracy of the results for the undefined products are questionable.
*I am not affiliated to Stringster in any manner of form. I am just curious and installed the app to try it out
