• TennisTension is the FIRST WORKING mobile app that instantly measures the momentous string tension of a tennis racquet with extreme consistency and accuracy. We, the developers, GUARANTEE full satisfaction if you trust and buy TennisTension. The error of the measurements is less than 0.2 kg. Tracks the TENSION LOSS. It records and analyzes the ringing sound heard from the strings when they are hit with a stiff object (pen, pencil, another racquet, fingernails etc.).
• Systematically tested with different racquets and strings by players at different level of play - from beginners to ATP professionals.
• 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.
• 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.
• Parameters to preset: head size; string pattern; main and cross string thicknesses and types; string opening size; stringing type. If some of them are not defined, the app will use the average default values or the last values the user put.

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

Instructions for use

- The user has to learn how to produce the proper ringing sound close (2 to 10 cm) and in front of the phone microphone. Find the microphone which uses single, very small hole either at the top or at the bottom of the phone.
- Remove the dampener - if you have.
- Tap the racquet string very gently several times every 1 or 2 sec. with a stiff object. The best way is with pen or pencil, or use another racquet, fingernails, etc.
- While ringing, the resonating racquet string must stay 2 to 10 cm from the microphone, in front of it, especially in a noisier environment.
- To receive the exact momentous string tension, define all the necessary racquet and string parameters. If you don't know some of the them, default average values are taken for the calculations, or the last values that the user put it in.
- 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).
- String tensions of hybrid strings could be measured as well.
- The error of the measurement result is less than 0.2 kg.
- Calibration is provided, though it is not necessary to make it.

- TennisTension will help you understand your tennis game, find the right string models for you and the relevant string tension. In few months time you will be able to improve all your tennis ability by better understanding and controlling the huge role of the strings and their actual tension during play.
- TennisTension will serve you through all your tennis career.

Instructions for use

- Mind the tension loss!
- Remove the dampener!
- Hybrid string mode can be chosen in the settings.
- If you wish, change the default parameters of the string model types, string thicknesses, string pattern,stringer’s style, head size, the influence of the racquet’s frame and grommets.
- Soon TennisTension Ltd will release a new version of the app with the feature called Fixed racquet/string/stringer configuration (for details read the instructions while implementing every new configuration). With this feature every user will be able to implement his own racquet's and string's model configuration and also taking into account the role of the specific stringer's working style.
- To make a measurement, tap gently once or several times the center of the string with a hard object (another racquet, fingernails, finger knuckles etc.), while keeping the resonating racquet string as near as possible and in front of the phone microphone (usually mounted at the bottom of the phone).
- Be careful not to touch the string with your fingers while measuring.
- The measurement result shows the average tension between main and cross strings of the racquet (for example, if a racquet is strung 25/24 kg the app will measures 24.5 kg).
- The error of the measurement result is less than 0.1kg.
- Read the FAQs section for more information
