StringSense: Tennis Strings

Track string health & know when to restring. Science-based string tracker.

Dead strings cost you power, spin, and control — but how do you know when it's time to restring? StringSense tells you exactly when your strings are due, so you always step on court with confidence.

SCIENCE-BASED STRING HEALTH — NOT JUST A TIMER

Most players guess when to restring. StringSense takes a different approach: a science-based string health algorithm that calculates real-time wear for every racquet you own.

The model factors in everything that affects string tension loss and lifespan:
• String type — polyester, gut, hybrid setup, multifilament, or synthetic gut
• Playing time and session intensity
• Court surface — clay, hard court, or indoor
• Temperature and weather conditions
• Player level and competition play
• Fresh balls, which increase string wear

Your strings don't just age on a calendar — they wear differently depending on how and where you play. StringSense understands that.

TRUE HYBRID SUPPORT

Play with a hybrid setup? StringSense v3.0 tracks your mains and crosses 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. Mains carry 60% of the wear weight, crosses 40%. No more averaged guesswork.

HOW IT WORKS

1. Add your racquet and log your string job with string type and tension.
2. Record your tennis 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 — LEARNS YOUR PREFERENCES

After each session, StringSense asks how your strings felt: crisp, normal, or mushy. This teaches the app your feel preferences over time, so restring recommendations become more accurate.

YOUR DASHBOARD AT A GLANCE

See all your racquets with live string health indicators. Track total play hours, average string condition, and tension history with detailed graphs. Swipe through your racquets, tap for details, and stay on top of racquet maintenance.

TENNIS SESSION LOG

Log every session with details that matter: duration, surface, intensity, indoor or outdoor, temperature, competition or practice, and ball condition. StringSense uses all of this for its string wear indicator — a health score that reflects real usage, not just time.

Your personal tennis diary and equipment tracker combined.
