Cello Tuner is a focused Android tuning tool for cellists who need quick pitch checks during practice, lessons, rehearsals, or performances. It listens through the phone microphone, identifies the note being played, and uses a real-time needle to show whether the string is sharp, flat, or centered. Players can work with the standard C, G, D, and A strings, read the detected frequency, or tap reference tones to tune by ear. Chromatic coverage, microphone sensitivity controls, and an offline-friendly design make it useful for both beginners and experienced musicians.
