About this app

Play tennis more effectively with fresh, lively strings!

Use "stringster for tennis" to analyze the condition and the tension (stringster PLUS) of your strings based on their sound.


- to monitor your string wear out over time
- to recognize the appropriate time to restring your racket
- to check your stringer’s performance


Playing your tennis racket with fresh, "lively" strings has decisive advantages:

- more feel for the ball and more controlled strokes
- higher repulsion power
- better shock absorption on ball impact reduces the "tennis elbow" risk

When the strings wear out, feel and control of the ball get lost. This will make your game more insecure. The fun of the game and the performance suffer.


Free of charge: Monitor the change in the string condition of up to 2 tennis racquets over the course of time. Select them from over 200 current tennis racquet models. And set up an unlimited number of new strings for these two rackets if the old ones are worn out or broken.

stringster PLUS: Monitor the change in the string condition of an unlimited number of tennis racquets. Beyond that access the information on their tension levels in kg or lbs - based on the individual data of over 400 current tennis string models. Including measurement of freely combinable hybrid setups.

Stringster PLUS is available for subscription as either monthly, seasonal or yearly auto-renewable subscriptions. Payment will be charged to your Play Store account upon the expiration of a free trial period. Subscription automatically renews unless the subscription is canceled or auto-renew turned off at least 24 hours before the expiration of the free trial period or the current subscription period. Subscription may be managed and auto-renewal may be turned off by going to Play Store account settings after purchase.
