Stop guessing, start tracking. String Master is the ultimate performance-tracking companion for tennis players who demand the best from their equipment. Whether you are a casual player or a competitive athlete, your string setup dictates your game. String Master helps you record, analyze, and discover the perfect string configurations tailored to your unique playing style. [Major New Updates & Premium Features] • Smart Recommendation Wizard & Normalized Engine Finding your next string is now effortless. Our 3-step recommendation wizard uses lab-tested data (stiffness, spin potential, tension loss, energy return) and scales them using min-max normalization to prescribe the perfect setup matching your game. • Dynamic Activity Calendar & Backdating Visualize your active string health on a color-coded calendar. Log past sessions, backfill older stringing jobs, and edit durations with instant, automatic health percentage recalculations. • Playability & Environmental Logging Go beyond time tracking.
