What Cleartune is
Cleartune is a chromatic instrument tuner and pitch pipe for iOS and macOS. It uses a device’s built-in microphone to tune guitar, bass, bowed strings, woodwinds, brass, piano, tympani, and other instruments that can sustain a tone. Its interface combines a note wheel, fine-tuning meter, and 25-cent range display, with listed accuracy of ±0.01 semitone (±1 cent). Users can select or define temperaments and note notations, including solfège and a built-in violin-family temperament. The app supports transposing instruments, automatic reference-note calibration, and adjustable A4 calibration in 0.1 Hz increments. Its pitch pipe generates tones with selectable waveforms. Note selection may be automatic or manual, and needle damping is available. Cleartune costs $3.99, paid once. There is no free plan or trial. The latest listed version is 2.3, dated June 16, 2020.
