Great for tracking string tension over time
I’ve been using this for one month now and it's become part of my routine before matches. You just tap the strings and get a reading. What surprised me is how consistent the readings are when I tracked them over time. I like the chart readings and trends. I use Luxilon Alu Power and those strings lose tension fast, so being able to actually see the drop over a week or two is really useful for knowing when my strings are dead and impacting my game. After getting my racquet restrung I calibrated it in the app and the absolute tension numbers lined up pretty well too. There's also a section where you can see what strings and racquets the pros use which is fun to browse. Can't believe this is free honestly. Wish I found it earlier.
