Spring season is here. Track your string health, log every session, and always know when it's time to restring. Play your best.
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.

StringSense 3.3 — Smart Check now learns.
What's new:
• Personalized Smart Check — the app learns the health level at which YOUR strings feel "mushy" and moves your restring recommendation right there. The more you check in, the sharper it gets.
• Restring recommendation on the racquet — a clear cue on the health score once you hit your personal threshold.
• Per-racquet history — your string feel over time, with feel icons on every session. Pro: the full history timeline with your threshold line.
• Pick your racquet from a catalog — choose your model when adding it (Babolat, Wilson, Head, Yonex, and more); weight, head size and string pattern fill in automatically. Plus type-ahead suggestions for 90+ strings.
• Improved readability — finer contrast in light and dark mode.
Plus smaller under-the-hood improvements.
