String Tracker – Tennis Restring Log Never wonder if your strings are dead again. String Tracker helps tennis players monitor string usage across multiple rackets, so you always know exactly when it's time to restring. Track String Wear Automatically Log every session in seconds. Enter how long you played and whether it was singles or doubles — String Tracker automatically calculates effective string wear (doubles count as 50%) and adds it to your racket's running total. A visual arc gauge shows you at a glance how close each racket is to the recommended 16–20 hour restring window. Full String Setup Records Record exactly what's in each racket — brand, model, gauge, and tension for both main and cross strings. Choose from a comprehensive library of major string brands including Babolat, Luxilon, Solinco, Tecnifibre, Wilson, Head, Yonex, Volkl, and more, or enter a custom string manually. Complete Session History Every session is saved with the date, time, duration, match type, and effective hours. You can manually set the date and time for each session, making it easy to log a match you forgot to record. Delete any entry if you made a mistake — the racket's total automatically adjusts. Two Racket Support Track two rackets independently. Each has its own usage counter, restring history, and string setup record, so you can rotate rackets without losing track of either one. Designed for Tennis Players Built with a clean, court-inspired dark interface that's easy to read courtside or at the club. No account required, no subscription — your data stays on your device.
