Practice With A Center Pitch

Pitch Drone keeps the music workflow narrow and clear: note, octave, A4 calibration, drone color, BPM, practice note, and clean export.

Reference Drone

Play a steady tone for long tones, choir entries, brass warmups, strings, and ear training.

A4 Calibration

Set A4 from 430 to 450 Hz in half-step increments for ensemble practice contexts.

Simple Metronome

Run a local click beside the tone without opening a full studio, sampler, or tuner screen.

Built For A Small Paid App

No login, no microphone recording, no uploaded audio, no server sync, and no analytics in 1.0. The app stays focused on one useful job: give musicians a clear local center pitch.
