E-Chord

This app displays guitar chord finger positions.
They are computationally-displayed, so they are also compatible with things such as alternate tunings and fraction chords, and they have overwhelming search capabilities even when compared to our company's G-Chord.

This chord app is distinctive for the fact that it doesn't use a premade database of finger positions; rather it takes the selected chord and calculates correct finger positionings, with the relative difficulty of each classified by color. You can do reverse lookups from any of the 24 frets, and the program can also handle "fraction" chords (D/C, C/E, etc.). The app can also display finger positions for alternate tunings.
The application accommodates left-handed players as well.
The program can save finger positions matching the tuning you are using at that time.
It is also possible to take a saved chord image and e-mail it as an attachment.
There is no limit to the amount of chords you can save. (iCloud saves are limited to about 1MB.)
Chords are color-coded by difficulty on the lookup and reverse lookup screens. You can indicate whether you want fingers positionings to be limited to three frets or to four frets. (Positions requiring five or more frets are avoided.)
The chord buttons displayed on the top page can be customized. Results from all designated string lookups can be added to the top page as a button. Also, it is possible to delete or rearrange buttons on the top page, or to reset it completely to its original state.
The application in its original state can currently add a minimum of roughly 1.2 million different chord buttons (including finger position variants of the same chord name) to the top page. With the addition of alternate tunings and "fraction" chords the number of finger positionings which can be looked up is 10 times higher still.
In the same way, chord names can be determined from finger position (reverse lookup). Please try it out!
