Wow and Flutter Turntable RPM

Are you sure your turntable is perfectly calibrated? Even high-end audio systems lose their true sound with a 0.1 RPM deviation.

Wow and Flutter is a professional-grade calibration tool designed for audiophiles. Simply place your phone on the platter. Using strictly the device's built-in gyroscope (no cameras, no vision AI, 100% offline), it measures your turntable's rotational speed and microscopic variations (Wow and Flutter) up to two decimal places. Experience the heavy brutalist analog VU meter interface and feel the haptic feedback when you hit the perfect 33.33 RPM.
