Description

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. · The 4536 money chords — all four variants: plain, 2-5-1, III7, 4531 · Canon, the fifties progression, turnarounds, twelve-bar blues · Jazz, gospel, rock and Andalusian progressions — twenty in all · Change the key and every chord follows: twelve keys, major and minor · The seven diatonic chords of the key stay pinned at the top · Hear it, or save it as one of your own ■ 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. ■ 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. Pro adds alternate-tuning fingerings to the chord dictionary. Buy it once. It is not a subscription. ■ A PROMISE Everything that is free today stays free. It will not move behind the paywall later. Available in English, Korean and Spanish. Contact: [email protected]
