Chord reference and chord finder for guitar, bass, banjo, ukulele, mandolin and bouzouki. Supports standard and alternate tunings and includes more than forty-five chord types: both simple and complicated ones used in jazz music, including slash chords.

You can display, compare and practice several different chords at once. They may be the chords of a song or different variations of the same chord.

You can adjust the complexity of the chord shapes shown according to your skill. In addition to the usual chord shapes, ChordAid lets you choose among more difficult chord shapes with two barres and big stretching between fingers.

Several strumming options or finger-picking style are available.
Supports left handed players.
You can translate chords from one instrument to another.

You can mark individual chord shapes as favorites. Then you can switch to a display mode that shows you favorite shapes only. In this way you can build a chord library of your own.

In a "Reverse Chord Finder" mode, you can select a few notes on the fretboard and the app will show you the names of the chords that match. You can then add the chord to the chord list and the app will show other fingerings.

The chord app I’ve always wanted.

Super powerful chord dictionary. Choose a chord, and a number of voicings will be presented in a column. Voicings can be favorited and filtered down to reduce clutter. I can run through all the chords in a song from iRealPro in a few minutes, screen shot the chords I want, and print a cheat sheet.

Crazy impressive flexibility. Multiple string instruments and tunings. I’m learning new tracks on guitar and mandolin so much faster now!

To the developer: Thank you! I’ll be recommending this to all my string playing friends.

Very basic.

Any chord requests comes back not available. I regret the purchase.

Developer Response ,

Hi, please check that the 'Favorites' mode isn't turned on (the star icon near the top right corner) or that you haven't turned on very restrictive filtering. You should definitely see many shapes for each chord.
You can always send us an email to and we will help you resolve the issue.
