Play badminton more effectively with a perfectly strung badminton racket! The stringster app measures the tension level of your strings by their sound. This helps you:

- to check your stringer’s performance
- to monitor the loss of tension over the course of time
- to identify the appropriate point of time for new strings

When the strings wear out, the precision and the touch of the racket get lost – just as a racing car’s wheels start spinning when its tires are worn out.

Playing your badminton racket with fresh strings has many advantages:

- higher repulsion power for longer clears and faster smashes
- better feel for the ball and more sensitive control
- better shock-damping performance for joint-protection at arm and shoulder

I have strung my victor lightfighter 7500 at 26 lbs. tested with stringster and it tells me the tension is 20lbs and the strings need replacing. I’ve not even used the racquet yet! I know the app is free but i wouldn’t recommend using it to determine string tension. There’s no way i could have lost 5 lbs of string tension over night

Finally got it...excellent

When I first used it I thought it was rubbish as it said the string is dead (a single red) a it needs replacing after I just string a racket. I improved my string technique and now it gives me 3 green (strings fresh). I now believe in the app

Crashes when opening!

Every time I open the app it opens in another language then closes immediately, not good at all 😔 Was very useful and informational before the update that has caused this.
