TennisTension for Android

11 things about TennisTension

1. • TennisTension is the FIRST WORKING mobile app that instantly measures the momentous string tension of a tennis racquet with extreme consistency and accuracy.

2. • At ATP Sofia 2019 in January, 3 from the seeded players tested, approved and gave recommendations for improvements, which we implemented: string pattern, hybrid stringing, string opening size influence, noise disruptions.

3. • If the user defines accurately all parameters of the tennis racquet and its string, then the error of the measurements will be less than 0.2 kg.

4. - TennisTension measures the average tension between main and cross strings of the racquet (for example, if a racquet is strung 25/24 kg, the measurement result will be 24.5 kg).

5. - To receive the exact momentous string tension, define all the necessary racquet and string parameters.

6. • Parameters to preset: head size; string pattern; main and cross string thicknesses and types; string opening size; stringing type.

7. - While ringing, the resonating racquet string must stay 2 to 10 cm from the microphone, in front of it, especially in a noisier environment.

8. Use the "Calibration" to cope COMPLETELY with all specific characteristics of every racquet, string and stringing machine/stringer combination.

9. - Tap the racquet string very gently several times every 1 or 2 sec.

10. - String tensions of hybrid strings could be measured as well.

11. - The user has to learn how to produce the proper ringing sound close (2 to 10 cm) and in front of the phone microphone.
