Full description

Tennis Tension Tracker helps you measure and track how your racket strings feel over time. Tap the strings, capture the pitch with your phone’s microphone, and see an estimated tension in pounds. Save readings per racket and stringing so you can spot tension loss and decide when it’s time to restring. Features: • Quick tap-to-measure tension tests • Multiple rackets with customer groups and stringing history • Large built-in racket and string libraries • Hybrid setups (different mains and crosses) • Tension history charts per racket • Optional custom presets for your own gear • 14-day free trial, then $1.00 USD/month via Google Play (cancel anytime in Play subscription settings) Built for players and stringers who care about consistent feel — from club nights to match day. Note: Results are estimates based on string vibration and your recorded string specs. Use them to track relative change over time; they are not a substitute for a calibrated tension meter.
