Audio Pitch Tuner

Real-time pitch tuner using your device’s microphone for instruments and vocals

Pitch Tuner is an app that uses your device’s microphone to detect pitch in real time.

It displays the detected sound as a note name, frequency (Hz), and cent deviation, and includes a clear meter and indicators that show whether the pitch is flat, in tune, or sharp.

The A4 reference pitch can be adjusted from 430 to 450 Hz, and transposition from -11 to +11 semitones is supported.

Pitch Tuner is a simple and easy-to-use tuning app for instrument practice, vocal training, and ensemble tuning.
