About this app

GrooveSpeed is a precision, ad free, turntable speed diagnostic tool for vinyl enthusiasts and audiophiles. Using your phone's built-in gyroscope and accelerometer, GrooveSpeed turns your Android device into a professional-grade tachometer — helping you verify and fine-tune your turntable's performance with no additional hardware required.

Simply place your phone flat on the platter, hit Start, and get an accurate, real-time picture of everything happening under your stylus.

Key Features:

• Privacy First: No tracking, no ads, no account needed. Your measurement data stays entirely on your device.

• Precision RPM Measurement: See your turntable's exact speed in real time, updated continuously using raw gyroscope sensor data. Supports 33 ⅓, 45, and 78 RPM modes.

• Wow & Flutter Analysis: Measures cyclic and random speed variations with industry-standard weighting modes (Unweighted and DIN-weighted). Know exactly how stable your platter is spinning.

• Pitch Deviation: Get a precise percentage reading of how fast or slow your deck is running relative to its target speed — indispensable when adjusting your turntable's pitch control.

• Platter Wobble: Detects lateral instability in your platter's rotation, helping identify worn bearings or unbalanced platters.

• Motor Rumble: Measures vertical vibration from your drive motor using the accelerometer, giving you a real-world read on motor noise floor.

• Live Strobe Visualization: A real-time animated strobe ring that visually represents your platter's drift, made to simulate the classic physical strobe disc experience.

• Live RPM Graph: A scrolling signal graph plots your instantaneous RPM over time — great for spotting recurring flutter patterns or belt-slip events.

• Polar Deviation Plot: A spatial chart showing how your platter's speed deviates across 360° of rotation, revealing eccentric or asymmetric wear patterns.

• Live Tuning Mode: Keep your screen alive indefinitely while you adjust your turntable's pitch control, letting you dial in the perfect 33.33 or 45.00 RPM.

• Session History & Sharing: Save your measurement sessions and share beautiful diagnostic report cards directly from the app.

GrooveSpeed is the professional-grade turntable diagnostic tool that fits in your pocket. Download it today and know exactly what your records are hearing.
