Pretty good

This app honestly works pretty well. I requested for a fresh stringing job at 26lbs and the app was +-0.05 lbs. Would recommend if you need a basic idea of where your tension is at

Might Work?

I can’t quite tell if this works well or not. But it is at least within +- 2lbs. I got my racket strung at 25lbs (assuming they did a perfect job) and after using the strings for a few weeks this app is saying it’s at 23lbs which is entirely possible. When I re-string my racket I will test again.
