StringTracker vs StringSense

StringTracker helps tennis players keep track of racket string life with a simple, focused workflow. Add your rackets, record when they were last strung, and update playtime after each session. StringTracker keeps a clear running total of hours played on each string job, so you can decide when it is time to restring based on your own playing habits. Track multiple rackets: Keep all your rackets in one place and see their current string age at a glance. Log playtime quickly: Add or subtract playtime with simple swipe actions using your preferred time increment. Set your restring target: Choose the number of play hours you consider optimal before restringing. Mark rackets as restrung: Reset playtime when you restring a racket while keeping your tracking simple. Organize your list: Rename, reorder, or remove rackets as your setup changes. StringTracker is built for players who want a lightweight way to manage racket maintenance without spreadsheets, notes, or complicated session logs.

Dead strings cost you power, spin, and control — but most players have no idea when it's time to restring. StringSense tells you exactly when your strings are due, so you always play with confidence. What Makes StringSense Different Unlike simple timers or tone-based tools, StringSense uses a science-informed string health model. It factors in your string type, playing time, court surface, temperature, intensity, player level, and your racquet's specs to calculate a real-time health score for every racquet you own. True Hybrid Support Play with a hybrid setup? StringSense tracks your mains and crosses string types separately. The algorithm calculates wear based on the actual materials — so a poly/gut hybrid gets a different health score than a poly/multi hybrid. No more averaged guesswork. Your Racquet Counts String pattern and head size change how fast your strings wear. A dense 18×20 on a small head spares them (up to 15% more string life); an open 16×19 on a big head punishes them (up to 13% less). Log string pattern, head size, and weight per racquet, all optional — or pick your model from the built-in catalog (Babolat, Wilson, Head, Yonex, and more) and the specs fill in automatically. How It Works 1. Add your racquet and log your string job with string type and tension. 2. Record your play sessions — duration, surface, intensity, and conditions. 3. Watch your string health score update automatically after every session. 4. Get a clear signal when it's time for fresh strings. Smart Check After each session, StringSense asks how your strings felt: crisp, normal, or mushy. Over time it learns the health level at which your strings feel dead to YOU and tunes your restring recommendation to match — the more you check in, the sharper it gets. Reminders You don't have to keep checking. StringSense tells you when your strings reach your personal restring threshold — the one it learned from your Smart Checks. One wear reminder per stringing, scheduled for the morning and never at night — your device decides the exact moment. Free, switched on once after your first string job, and off again in the Workshop whenever you like. Until you've logged sessions it stays quiet — with no play time there is nothing to estimate. Rating & favorites How did the last stringing play? StringSense asks once when it comes off the racquet: stars, five traits, a private note. Setups you want again become favorites — on your next string job, strings, types, gauges and tensions are pre-filled. Knowledge Base & Glossary Five string type guides explain character and warning signs. Plus a glossary from string pattern to settling — free, right in the Workshop.
