ChordAid: Chord Reference

ChordAid: Chord Reference is a chord reference and finder for guitar, bass, banjo, ukulele, mandolin and bouzouki. It supports standard and alternate tunings and includes more than 45 chord types, from simple triads to jazz extensions and slash chords. You can display, compare and practice several chords at once—these can be chords from a song or different variants of the same chord. Adjust the displayed complexity to match your skill, including difficult shapes with two barres and large finger stretches. Choose from strumming or finger-picking styles, and enjoy left-handed layouts.

ChordAid also translates chords between instruments, lets you mark favorites, and switch to a favorites-only view to build a personal chord library. In Reverse Chord Finder mode, you select a few notes on the fretboard and the app shows matching chord names; you can add the chord to your list and explore other fingerings. Supported instruments and tunings include Guitar (6 strings with many tunings), Bass (4 or 5 strings), Ukulele, Mandolin, Bouzouki, Guitalele, Banjo (5 and 4 strings), and Waldzither.
