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

Poorly programmed and inaccurate

The interface for adding other manufacture rackets is confusing, you have to add the name twice or it won’t work. Some times the save button disappears while selecting the size of the racket. And two rackets I tested, they are 23-24lb tension, measured to be 14.5 and 15.7 lb

Good app. Consistent results

Tried this app on 5 strung rackets. Yonex vtgz, nrgz, two as 11 and a duora 10. All strung at 22-24lbs. The result for a new strung nrgz is 24.9. A one week vtgz is 21.6, a four week as11 aerobite 20 and a eight week as11 aerosonic is 20.5. A half year duora 10 is 19.4. I measured several times by hitting the center of the rackets with other rackets. Results are pretty consistent. Difference is less than 0.1 lb.

I use electric head with prestretch and add two pounds for the center 4 main strings. So my rackets may be slightly tighter than 22. But the measure may still be 1-2 lbs higher. Overall, I think the app did give consistent results. I cannot say exactly how accurate it is. But it can definitely be used to measure how much tension your racket has lost since it was strung. Giving it is a free app, I have no complaints.

It’s a toy, not a tool

An amusing toy to goof around at courts if you were bored. It’s not a real tool to measure anything useful. You’re better off pressing strings with your thumbs to gauge string tension than using this app.
