Can’t get past what type of racquet. You select a drop down then keeps saying you haven’t selected anything. Complete and total dog feces ### 1/5 — Can’t add a racket *2024-10-30, version 2.1.10* Can’t add a racked - does not go past the string type page ### 1/5 — Doesn’t work *2024-10-19* Don’t bother ### 1/5 — The most Stupid thing ever *2024-03-28, version 2.1.0* Can NOT add any racquet at the stupid app ### 1/5 — Does not work *2024-03-01, version 2.1.0* Cannot add any racquet or string. ### 1/5 — Racquet drop-down not loading *2023-10-30* Wanted this app to work, but after recording the strings, it asks to pick the racquet, but the drop-down is blocked by the keyboard pop up. Can select (?), which I was able to get to the second page, but when I try to do the same for the string type it doesn’t pop up with any other fields. So can’t test the string tension. Kind of a waste. Hope they can fix the bugs. ### 1/5 — Garbage app, doesn’t work *2023-09-13* It asks for racquet and string names. Doesn’t recognize anything I put in. ### 3/5 — It works *2023-06-28* The app seems to work as I have tested 5 different rackets and the tension given is about correct but O don’t have anything to test against to prove but my newest racket was strung at 50lbs and after sitting for a while the. playing a 3 hour session it measured 47.6 lbs, about what you would expect. So far so good. ## Frequently asked questions about stringster for Tennis 2.0 ### What is stringster for Tennis? stringster for Tennis is a sports app that uses sound frequency to measure the tension and condition of your tennis racquet strings.
