About this app

50% of the character of a tennis racquet is determined by its frame, the other 50% by the strings - and their condition.

With "stringster" you measure the string tension of a racquet based on the sound frequency and you can regularly check the strings´ condition. This way you can identify the right time for a restringing to get the best out of your tennis racquet.


THE BENEFITS OF FRESH, LIVELY STRINGS:

- Performance: a more sensitive feedback of the string bed improves your feel for the ball and your control over the strokes

- Arm protection: a better shock absorption on ball impact reduces the risk of joint problems or "tennis elbow”


THIS IS HOW YOU USE THE STRINGSTER APP AS A STRINGER:

- Freshness Check: advise players on whether a racquet should be re-strung

- Stringing report: send your customers an automatically generated digital protocol of your control measurement directly after stringing

- Customer management: manage your customers and their racquets - also conveniently via tablet


RACQUETS AND STRINGS AVAILABLE IN THE STRINGSTER APP:

The measurement results of "stringster for tennis" are based on data from over 200 current tennis racquet models and over 600 different tennis string models, diameters and colors. All strings can be freely combined and measured as hybrid setups.


FREE APP USAGE:

Measure and monitor the change in string tension and condition of an unlimited number of tennis racquets. For all racquets, you can edit an unlimited number of new strings in the app when the old ones wear out or break.

Feels like an April fools prank. Stuck at 0% or no progress bar at all. No racket selection. Bad onboarding I to the app. I was told that it can also be used for Badminton rackets. Maybe so, but if this was ever true then they broke it. Which makes me curious, which sane person would let a useful and good app degrade and do nothing? 🚨 This is likely to be malware. And on second thought it can't be this hard to make the app work for other racket sports if you already figured out an "algorithm".

appealing GUI however I wasn't able to save one racquet. I entered the model, I found the strings, but regardless of the string age and times played, I wasn't able to save, hence I got no measurements

If string is not listed, the app suggests to enter ? however if you set the app to measure tension it doesn't do it. it says that string is fresh?! I want to know what tension to compare with my stringing machine. So, this app only reads tension if your during is listed.
