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.

That chord you can play but can't name — now you can look it up. ■ TUNER (every tuning, free) · Detects which string you played through the microphone · A headstock diagram shows which peg to turn, and which way · Supports both 3+3 (acoustic) and 6-in-line (electric) headstocks — they turn in opposite directions · Standard, Drop D, Half-Step Down, Whole-Step Down, Open G, Open D, DADGAD — all seven tunings are free ■ PRACTICE TOOLS · Build and save chord progressions · Chord transition trainer — change chords in time with a metronome · One Minute Changes — sixty seconds, counted by ear through the mic · Tap the tempo — tap along with a song to find its BPM · Backing loop — the progression keeps playing so you can play over it · Capo support — the shape you hold and the chord that sounds, side by side · Left-handed mode — diagrams mirrored ■ FREE, FOREVER · The whole chord dictionary — 12 roots, 22 qualities, every included shape · All twenty chord patterns, transposed to any of the twelve keys · Find by shape · Chord playback · The whole tuner — all seven tunings · Capo · Left-handed mode · Interval labels · Up to 2 saved chord progressions · Tap the tempo — find a song's BPM by tapping along · Listening to a progression once ■ CHORD ON PRO (one-time purchase) · Chord transition trainer — change chords in time with a metronome · One Minute Changes — the app counts your chord changes by ear · Backing loop — a progression looped with five strum patterns · Unlimited saved progressions · Alternate-tuning fingerings in the chord dictionary · Family Sharing supported All seven tuner modes are free.
