5 Great Guitar Chord Apps for iOS & Android

When I started taking guitar lessons, one of the first things I bought was a guitar chord book. It doesn’t matter whether your a beginner learning a “G major” chord, or an advanced player looking for jazz inversions; chord libraries are essential for building your musical vocabulary.

Here are 5 great guitar chord apps that you can keep handy on your mobile device for lessons, class, or home practice. None of them may equal Ted Greene’s “Chord Chemistry”, but they get close.

Couple quick notes:

Guitar Chord App List

Review: (10,616) 4.1 stars
By: Thomas Grapperon | website
Platform: Android
Overall Reviews: 10,638 (4.1 stars)
Price: Free

The Chord! set of apps for iOS and Android provide “the simplest and the most complete chords and scales app for guitar or any fretted instrument like bass, ukulele, banjo, etc.”

Chord! sets itself apart by computing all possible fingerings for a given chord, rather than simply storing a set of diagram pics.

This Chord! Free (Guitar Chords) app for Android boasts some impressive numbers with over 1million downloads, and over 10k reviews at 4.1 stars.

This free version is somewhat limited to a “fully functional chord search, but only 5 scales instead of 400 and 8 tunings, no reverse chord and scale search and no custom tunings database.”

A definitive chord library. 7 Chords, by Handplant Studios, provides over 1500 easy-to-read chord diagrams in a nice clean format. This is a great reference guide for new to mid-level players.

The iOS version of the Chord! suite of guitar chord apps is fairly young, but seems to be getting great reviews. The app includes chord references, scales, and even an engine for making your own songsheets.
