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. Log how your strings feel (Soft, Crisp, Stiff, or Dead Poly), track weather conditions (Sunny, Humid, Cloudy), and record temperatures to understand how environment impacts your tension. • Community Insights & Lifespan Rankings Access real-time community statistics and trends. View the top average string lifespan rankings based on thousands of hours of real player data. (Access is granted to active members with a minimum of 4 hours of logged play over the past 14 days.) • Advanced Racket Specifications Track customized parameters for every racket in your bag. Log weight (g), stiffness (ra), swing weight (kg/cm²), balance point (mm), serial numbers, and custom tuning notes (lead tape, grip details). • Smart Restring & Terminology Polish Log a new job in 3 seconds! Tap "Restring" to clone your previous setup (racket, string, tension). Terminology has been audited and standardized to "History" across 10 languages. • Social Authentication & Data Migration Log in instantly with Google or Apple Sign-In. Seamlessly migrate your entire guest mode racket and stringing history to your permanent account in one click. [Core Features] • Restring Reminders: Set custom notifications (90 days or health below 20%) to prevent arm strain and maintain peak playability. • Hybrid Setup Support: Independently log mains and crosses (different brands, gauges, and tensions). • 10-Language Expert Guides: Tap the info (i) icons to read explanations of string materials and metrics, fully localized in 10 languages (EN, KO, ES, JA, ZH, ZH_Hant, DE, FR, IT, PT).
