## Description

▶ Know exactly when to restring. Pluck a main string, hold your phone&#39;s mic close, and the app reads the vibration frequency to estimate the tension of your stringbed in kilograms or pounds.<br><br>▶ Set up a profile for each frame: head size, string type and gauge for tennis, squash or badminton. The physics of a vibrating string turns pitch into a tension figure you can compare over time.<br><br>▶ Watch the drop. Tension falls even when you are not playing, so a history graph shows how much softer your bed has gotten since the day it was fresh, like minus fifteen percent and counting.<br><br>▶ Set a threshold and get a reminder when your bed has dropped past the feel you like, so a restring is never a surprise mid match.<br><br>▶ Save several racquets, log each measurement, and share a clean result card. Works on device, no account needed.<br><br>Readings are relative estimates that depend on your frame and string, and are best used to track change over time rather than as a certified gauge. Results vary with technique and setup.
