Piano Tuner is a 12-note chromatic scale strobe tuner application that utilizes audio input devices such as built-in microphone, line-in, and iSight.

Strobe tuners are extremely accurate compare to regular tuners with a needle or LEDs. The slightest difference between the actual pitch and the ideal pitch accumulates over time and appears as a movement on the strobe tuning meter.

Piano Tuner can be used by someone who wants to learn how to tune a piano by using a tuning lever and also be used by a professional piano tuner to help the tuning process.
