Chord ON: Guitar Chords, Tuner

New Chord Patterns tab - 20 progressions, from the 4536 money chords to canon and 12-bar blues, in any key. The shape finder now draws a real fretboard.

Find, hear, and practice guitar chords. No ads, no subscription.

4536, canon, twelve-bar blues - twenty progressions people actually play, in any key. Don't know a chord's name? Tap the shape you are holding and Chord ON tells you. Tuner and chord-change practice are in the same app, and all of it works offline.

Every shape is automatically verified: that its notes spell the chord, that the root is in the bass, and that the stretch is within reach.

■ WHAT MAKES THIS DIFFERENT

· No subscription — buy once, keep it. No recurring charges. · No ads — not even in the free version. · Offline — chord lookup, playback, shape search, tuning and practice all work without a connection. (Purchasing or restoring Pro needs the App Store.) · No auto-renewal — Chord ON Pro is a one-time purchase.

■ CHORD PATTERNS (all free)

The progressions you reach for when writing or backing a song, in any key.

■ CHORD DICTIONARY

· 12 roots x 22 chord qualities · Multiple ways to play each chord, from open position up the neck · A common standard fingering is shown first · Color-coded fingers, numbered too, so they read for colorblind players · Hear it — strum or arpeggio · Interval labels (R, 3, b7) to understand how a chord is built · Chord names explained — why this chord is called what it is called

■ FIND BY SHAPE

Tap the strings the way you are holding them and Chord ON names the chord. Strings are drawn as strings — the 6th thick, the 1st thin — with position markers where a real fretboard has them. That chord you can play but can't name — now you can look it up.
