Guitar Toolkit –iPhone App
Available at Apple’s App Store, Guitar Toolkit provides a super- accurate chromatic tuner for 6- and 12-string guitars, 4-, 5- and 6-string bass, banjo, mandolin, and ukulele. It covers standard and alternate tunings for each instrument and also provides a library of over 500,000 chords.
Even cooler, just touch the notes on the fret board to form
a chord, and it’ll tell you what chord it is!
The app also provides a metronome that can be set to a dozen different time signatures, for the King Crimson and Zeppelin fan within you. Guitar Toolkit even has a “lefty mode” that adjusts all chords and scales for left-handed players.
