Never guess when to restring! StringSense tracks your string health based on play sessions, intensity, and player level. Smart Check learns from your feedback. StringSense – Smart Tennis String Tracker Never guess when your strings need replacing! StringSense tracks your string health based on your play sessions, playing style, and player level — so you always know the perfect time to restring. SMART STRING HEALTH Your strings wear down with every session. StringSense calculates their condition in real time — factoring in play duration, intensity, surface, temperature, string type, and your player level. A battery-style indicator shows wear at a glance. • Adaptive health calculation based on your player level • Choose between Recreational, Club, or Competitive/Pro • Predictions for remaining play time and matches • Color-coded battery bar: green → yellow → red SMART CHECK – LEARNS FROM YOU After each session, rate how your strings feel: Crisp, Normal, or Mushy. StringSense uses your feedback to fine-tune its predictions — the more you play, the smarter it gets. SESSION TRACKING Log your sessions in seconds. Pick duration, intensity, surface type, temperature, and more. • Duration from 30 min to 3 hours • Normal or match play intensity • Surface: Clay, Hard, Grass, Carpet • Temperature and cold/wet conditions • Tap any session to edit it inline RACQUET MANAGEMENT Keep all your racquets organized. Add brand, model, and custom names. Long-press to reorder your dashboard with drag & drop — your layout syncs automatically. • Drag & drop reordering with haptic feedback • Swipe to delete racquets, sessions, or string jobs • Health badge on every card RESTRING HISTORY Document every string job with tension values, string type, and date. Track your tension over time with an interactive graph. • Polyester, Multifilament, Hybrid, Synthetic Gut & Natural Gut • Tension history graph (Pro) PLAYER LEVEL Not every player wears out strings the same way. Recreational players enjoy longer string life, while competitive players with heavy topspin get faster, more accurate wear predictions. DESIGNED FOR MOBILE • Dark mode, light mode, or match your system • English and German language support • Guided onboarding tour • Haptic feedback for a native feel PRO The free version tracks one racquet with full functionality. Upgrade to Pro for: • Unlimited racquets • Detailed tension health graphs • Data export (CSV / JSON) WHY STRINGSENSE?
