## Description

CarlTune is a free chromatic tuner that uses your device microphone to analyze sound and display the pitch, frequency, octave, and cent difference with intuitive visuals like analog clocks.

It offers a wide range of tunings for instruments (guitar, bass, ukulele, violin, cello, mandolin, and more), plus a universal chromatic interface for non-instrument sounds. Notable features include color customization, multiple notation options (US/Europe/Korea/Japan/India), screen orientation support, adjustable cent ranges, transposition with concert pitch, and a piano keyboard/Pitch Pipe view. All core features are free, with an in-app purchase to remove ads.
