StringSense

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-based string health model. It factors in your string type, playing time, court surface, temperature, intensity, and player level to calculate a real-time health score for every racquet you own. Your strings don't just age — they wear differently depending on how and where you play. StringSense understands that. 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. 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, this teaches the app your personal preferences — so recommendations become even more accurate. Your Dashboard at a Glance See all your racquets in one place with live health indicators. Track your total play hours, average string health, and tension history with detailed graphs. Swipe through your racquets, tap for details, and stay on top of your equipment. Works Offline No Wi-Fi at the club? No problem. StringSense stores everything locally and syncs automatically when you're back online. Your data is always available, on or off the court. StringSense Pro The free version gives you full access for one racquet. When you're ready for more: • Unlimited racquets • Detailed tension graphs • CSV data export • Support ongoing development Privacy First Your data belongs to you. StringSense uses no tracking, no analytics, and no ads. Your racquet and session data is stored securely in your personal account and never shared. Whether you're a club player who strings every few months, a tournament competitor who restrings weekly, or a weekend warrior who just wants to know when it's time — StringSense keeps your equipment in peak condition. Download StringSense and never play on dead strings again.
