PitchLab Pro

Why settle for guesswork when tuning your instrument?

PitchLab Pro turns your Android device into a precision chromatic tuner, signal generator, and pitch analyzer — all in one professional-grade tool. Whether you are a luthier setting intonation, a guitarist tuning in a noisy backstage, or a brass player checking harmonic overtones, this app delivers laboratory-accurate readings without requiring external hardware.

Core functionality and tools

The app operates in multiple modes to cover every tuning scenario. The chromatic tuner displays real-time pitch detection with a strobe-like display, showing both the note name (C, C#, D, etc.) and the cent deviation from 0.0 cents. A needle-style meter provides visual feedback, while an audible tone generator lets you tune by ear. The spectrum analyzer mode plots frequency distribution across the audible range, helping you identify resonant peaks, wolf tones, or string harmonics. A signal generator outputs sine, square, sawtooth, and triangle waves from 20 Hz to 20 kHz — useful for testing speaker response or calibrating audio equipment. All measurements update at a rate of 50 milliseconds, ensuring you catch even rapid pitch bends.

Key advantages for musicians

• Real-time chromatic tuner with strobe display and cent deviation readout
• Built-in signal generator with four waveform types and adjustable frequency range
• Full spectrum analyzer for visualizing harmonic content and overtones
• Customizable reference pitch (A4 = 440 Hz, adjustable from 400 to 480 Hz)
• Automatic pitch detection with 0.1 cent precision and 50 ms response time
