Tuner by Piascore

What Tuner by Piascore is

Tuner by Piascore is an iPhone and iPad app that combines a chromatic instrument tuner with a pitch pipe. It listens through the device’s built-in microphone and covers notes from E1 to A8. Piascore states accuracy of ±0.01 semitone (±1 cent). Its display includes a needle meter, a 50-cent fine-tuning view, an LED indicator showing whether pitch is high or low, and a power spectrum indicator. A tone generator can provide reference notes, with automatic reference-note calibration available. The app supports English, Solfège, and Northern European notation, transposition from -6 (F#) to +5 (F), and temperaments such as equal temperament, just intonation, and Kirnberger III. Alternate tunings and a custom reference pitch are supported. Tuner Lite is free, while Full costs $4.99 USD once and adds custom temperaments, transposition, notations, and current-frequency display.

Who it suits

It suits iPhone or iPad musicians who need chromatic tuning, reference tones, and multiple notation or temperament choices. Piascore describes it as fitting any kind of music.

Limits

Lite is free and has a different feature set from Full; current-frequency display is listed for Full but not Lite. Full costs $4.99 USD once and adds custom temperaments, transposition, and notations.
