Now available from Apple’s App store is an iPhone/iPad/iPod touch version of TC Electronic’s PolyTune guitar tuner, which allows checking the tuning of all guitar strings simultaneously. This 1:1 port of TC’s award-winning PolyTune pedal tuner offers the exact same tuning technology and features found in the pedal version. It also offers an onboard chromatic tuner with ±0.5 cent accuracy.
Polyphonic and Chromatic modes both work for guitar and a 4-, 5- and 6-string bass used with an iPhone or an iPad. The internal mic allows instant tuning of acoustic guitars; for tuning electric guitars, a mini-jack to ¼-inch adapter is required.
The first 25,000 download copies of the PolyTune iPhone App are offered free of charge; afterward the price is going to be $9.99.
