String Master vs RacketLog

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.

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.

See total play time, session counts, match and practice splits, your most active day, longest weekly streak, and a month-by-month activity breakdown.
