SweetSpot: Racket Tension

Badminton String Meter

Free · In-App Purchases · Designed for iPad. Not verified for macOS.

Measure badminton racket string tension in seconds using only your iPhone microphone. 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.
