pTune

pTune is a focused guitar tuner for players who want a clear, fast display without extra noise. Start in Chromatic mode for accurate single-note tuning, switch to Polyphonic mode to check all open strings at once, or use the built-in metronome for practice with time signatures and accent groupings. Features: - Chromatic tuner for single-note tuning across the guitar range - Polyphonic guitar tuning for standard and alternate tunings - Clear LED-style cents display for flat, sharp, and in-tune feedback - Calibrated A4 reference from 432 Hz to 448 Hz - Fast, medium, and slow response modes - Built-in metronome with tap tempo, time signatures, and accent groupings - Guitar-finish pedal skins including cherry burst, natural maple, blue flame, and charcoal burl - Noise gate and harmonic filtering tuned on real guitar tests - English and Turkish interface pTune listens through your device microphone. For best results, tune in a reasonably quiet room and play one string at a time in Chromatic mode, or strum open strings in Polyphonic mode.
