RacquetTuner analisi dell'app per 28 gennaio

RacquetTuner uses advanced audio analysis to measure your racquet string tension instantly. Simply tap your strings and get accurate readings in seconds. Perfect for tennis, badminton, squash, and racquetball players who want to maintain peak racquet performance and know exactly when to restring. ACCURATE STRING TENSION MEASUREMENT RacquetTuner analyzes the sound frequency produced when you tap your strings to calculate tension with precision. The app detects changes as small as 0.1 kg (0.2 lb), giving you reliable data you can trust. The measurement is based on proven physics: string vibration frequency is directly related to tension. Higher tension produces higher frequency sounds, and our algorithm converts this into accurate tension values. HOW IT WORKS 1. Select your racquet and sport type 2. Tap the center of your string bed 3. View instant tension reading with accuracy indicator 4. Save measurements to track tension loss over time FEATURES String Tension Measurement - Instant readings from audio analysis - Accuracy indicator shows measurement quality - Real-time waveform visualization - Support for metric (kg) and imperial (lb) units Swingweight Calculator - Calculate swingweight from racquet parameters - Simulate adding lead tape at different positions - Optimize balance point for your playing style - Visual racquet diagram with weight markers Stiffness Calculator (Premium) - Model stringbed stiffness from tension and head size - Compare power vs control characteristics - Load-displacement curve visualization - Simulate different string types Racquet Profiles - Store multiple racquet configurations - Track tension history for each racquet - Record string type and stringing date - Export measurement data to CSV SUPPORTED SPORTS Tennis - Standard tension range 18-32 kg Badminton - Standard tension range 9-14 kg Squash - Standard tension range 11-16 kg Racquetball - Standard tension range 14-22 kg WHY MEASURE STRING TENSION String tension drops immediately after stringing and continues to decrease with play. After two months, strings typically lose half their initial tension. This affects: - Shot control and accuracy - Power and ball speed - Spin generation - Comfort and arm health Regular tension monitoring helps you maintain consistent performance and decide the optimal time to restring.
