Macworld 2010 - Guitar Tuner iPhone app

Michael Butler interviews the Guitar Tuner creator. Overview GuitarToolkit is a collection of essential guitar utilities for your iPhone and 2nd generation iPod touch. All for just US $9.99. Chromatic Tuner Using the iPhone's microphone, GuitarToolkit provides a highly accurate chromatic tuner. You can tune to any musical note or to a specific tuning. Need to see it on stage? The high contrast mode is a perfect fit. Scales Choose from a list of scales for each note. You can even see scales for any tuning you choose. The interactive fretboard means you can just touch a note to hear exactly what it sounds like. Chord Library With over 500,000 chords, you can ditch those chord books you've been carrying around. Need to hear what a chord sounds like? No problem, just give it a strum. GuitarToolkit also support chords for alternate tunings! Chord Finder Playing around on your guitar, find some random fingering that sounds cool, and want to know what chord it is? GuitarToolkit's got your back. In Chord Finder mode, just place markers on the right frets and you'll see what chords it represents. Metronome GuitarToolkit also includes a precisely accurate metronome with 13 different sound effects and 12 time signatures. The metronome includes a visible flash option and a tempo tap pad. Custom Tunings GuitarToolkit comes with a wide range of alternate tunings, but if you've got a favorite that's missing, you can create your own with just a few simple clicks. Supported Instruments GuitarToolkit provides full support for 6 and 12 string Guitar, 4, 5 and 6 string Bass, Banjo, Ukulele and Mandolin. Lefties Welcome! Each supported instrument also has a "lefty mode" option which adjusts chords and scales to reflect those on a left-handed guitar.
