RacketLog

RacketLog takes the guesswork out of restringing. Track how long your strings have been in, how many hours you've played on them, and get notified when it's time for a fresh set. Whether you play twice a week or every day, RacketLog keeps your setup dialled in so your strings never hold you back. HOW IT WORKS RacketLog tracks string wear using two factors: play time and string age. Strings lose tension and feel over time, even when you're not playing. RacketLog monitors both and warns you when either limit is reached — whichever comes first. You set the targets. RacketLog does the rest. QUICK SESSION LOGGING Log play time in one tap from the home screen. Choose from preset durations or enter a custom session with date, duration, type (practice or match), court surface, and notes. Set your preferred defaults so every quick log matches how you actually play. STRING JOB TRACKING Record every restring with full details — brand, model, gauge, material, tension, stringer, colour, and cost. Set up a full bed or hybrid with separate mains and crosses. When you restring, copy your previous setup with one tap. Rate each string job across seven categories: durability, control, power, spin, comfort, feel, and appearance. Over time, your ratings help you find the string that suits your game. SMART WEAR TRACKING A visual gauge on every racket card shows remaining string life at a glance. Four status levels keep you informed: • Healthy — strings are fresh • Heads-up — approaching your target • Replace soon — time to book a restring • Overdue — past your recommended limit Targets are fully customisable by string material. Poly, multifilament, synthetic gut, and natural gut each have their own defaults, and you can adjust them to match your feel. BUILT-IN CATALOGS Choose from preset lists of major racket and string brands. String selection automatically detects the material type. Searchable pickers make setup fast, and manual entry is always available. RACKET MANAGEMENT Store your racket details — brand, model, grip size, string pattern, purchase date, price, and notes. Add a photo from your camera or library. Archive rackets you're no longer using to keep a clean home screen without losing any history. STATISTICS & INSIGHTS View stats across all rackets or drill into one. See total play time, session counts, match and practice splits, your most active day, longest weekly streak, and a month-by-month activity breakdown. Track total spending, average cost per restring, and cost per hour of play. NOTIFICATIONS Get push notifications when your strings reach heads-up, replace soon, or overdue status. Never get caught with dead strings before a match. BACKUP & EXPORT Export all your data as a readable JSON file. Save it to Files, iCloud Drive, or any cloud service for safekeeping. FREE & PREMIUM Track one racket with every feature — completely free. Upgrade to Premium for unlimited rackets. Download RacketLog and take control of your string setup.

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.
