D'Addario D'Tune is the quintessential digital tuner for iPhone brought to you by D'Addario & Company, Inc., he world's largest designer, manufacturer and distributor of musical instrument accessories.

Combining rapid and precise state-of-the-art pitch detection technology for iPhone OS with Apple's proven touch-screen controls, D'Addario D'Tune turns your iPhone or iPod touch into the ultimate portable instrument tuner. Dedicated modes for guitar, bass, violin, banjo and other stringed instruments offer the most reliable pitch measurement on any handheld platform.
