8月31日 的 SweetSpot: Racket Tension 應用程式分析

Measure badminton string tension with your iPhone. SweetSpot listens to the sound of your racket strings and estimates tension from the vibration frequency. It helps you check a fresh restring, compare rackets, and see when your strings are starting to lose their feel. Why players use SweetSpot: • Estimate string tension in seconds • Track tension history for each racket • Save racket profiles with string gauge and head shape • Compare readings after restrings and between sessions • Get guided tap detection for cleaner measurements • No separate tension meter required Built for badminton players, coaches, and stringers who want a quick way to monitor racket setup. For best results, measure in a quiet room, use the correct string gauge, and compare readings over time on the same racket.
