The Guitar App has an interactive fret board, a chord calculator, and a chord player. The primary purpose of this app is to provide a tool to guitar players of any level that let's them see chords for any tuning. The secondary purpose, and more fun use, is the chord pad player which let's you assign chords to 15 different buttons and play with chord progressions.
The chord reference feature has as many chord variations that could be found ranging from standard chords to many less common. It also has a wide variety of predefined tunings, as well as a custom tuning mode that let's players create their own tunings. What is unique is that the chords are calculated on the fly using an algorithm developed just for this app using user configured settings - these settings let you change the number of fingers and hand stretch to match your own abilities.
This app features real guitar sound (not synthesized) with clean and distortion tones and functions like an interactive chord finder that shows all notes on the neck for any tuning. You've acces to a total of 29 defined tunings and 54 different chord types, with user customizable chord generation parameters plus the ability to create and save your own chords and tunings. Both left and right handed players can play back their chords using a pad like interface.
Other than that "The Guitar App" can also act as just a tuner!!
