Cleartune is a chromatic instrument tuner and pitch pipe that allows you to quickly and accurately tune up using the built-in mic in your iPhone, iPad, iPod Touch or Android device.

Cleartune features a unique "note wheel" interface allowing you to quickly find your pitch, paired with a highly responsive fine-tuning meter for the perfect tune.

With support for custom temperaments, transposition, notations such as solfège, adjustable calibration and more, Cleartune packs more power than most pro tuners, yet is simple enough for everyone to use.

Cleartune can tune acoustic or electric guitar, bass, bowed strings, woodwinds, brass, piano, tympani, tablas and any other instrument that can sustain a tone.
