PitchLab Lite

Need a precise tuner for your instrument without the clutter?

PitchLab Lite delivers a professional-grade chromatic tuner and pitch generator, engineered for musicians who demand accuracy. Whether you’re tuning a guitar, violin, ukulele, or wind instrument, this app converts your device’s microphone into a real-time frequency analyzer. It eliminates guesswork by displaying the exact note, cents deviation, and frequency in Hz, helping you achieve perfect intonation in noisy environments or quiet practice rooms.

Core Tools and Functionality

The app operates in three primary modes: Chromatic Tuner, Pitch Fork, and Signal Generator. The chromatic tuner continuously listens via the microphone, showing the closest note (e.g., A4, Bb3) with a ±50 cents needle meter. The pitch fork mode lets you tap a note to hear a reference tone, adjustable from C0 to B8. The signal generator produces sine, square, triangle, or sawtooth waveforms at user-defined frequencies, useful for audio equipment testing or ear training. A strobe display option provides ultra-precise visual feedback, where a spinning pattern stops when the pitch is exactly in tune.
