ChordCoach is a complete guitar chord workshop: a 355-voicing chord book, a fretboard you can build chords on, and a library of the progressions that built popular music. THE CHORD BOOK Every chord in every key — major, minor, dominant 7th, major 7th, minor 7th, suspended and more — and every chord comes with several ways to play it. Take C major open at the nut, or as an A shape at the 3rd fret, an E shape at the 8th, a D shape at the 10th. Search by chord, by key, or by flavour and it's there in a keystroke. Each shape is drawn on a clean six-string diagram with numbered circles showing exactly which finger goes where, plus open and muted markers so you always know which strings to play. Tap any string to hear its note, or press Play Chord to strum the whole shape with real-time plucked-string sound. Every string is labelled with the note it sounds, so a little theory comes along for free. THE CHORD BUILDER Put your own notes anywhere on a full 15-fret neck and the app names what you've spelled — the chord, its inversion, and what each note is doing inside it. Strum it, spell it out one note at a time, or open it in the chord book. It's the fastest way to understand why a shape sounds the way it does. THE PROGRESSIONS 29 progressions, from the three-chord trick to the doo-wop changes to the 12-bar blues, each with the songs that made it famous. Play any of them in any of the 12 keys, at any tempo, and the chord diagrams move with you. Tap a song and the whole page shifts into that record's key and tempo — so what's on screen is what's on the record. FAVOURITES Star the voicings and progressions you're working on and they're waiting for you on the next practice session. DESIGNED FOR IPAD On iPad the chord book becomes a sidebar with the diagram beside it, the neck stretches out to full size, and every page uses the room it's given. • 355 voicings across every key and flavour • Search by chord, key or flavour • A 15-fret builder that names what you play • 29 progressions with the songs behind them • Any key, any tempo, chords that follow along • Favourites that persist between sessions • No account, no ads, no tracking — works completely offline Whether you are pressing your very first chord or working out why a voicing up the neck sounds different, ChordCoach helps it click faster. Pick up your guitar and start playing.

Verdict
The clearest difference is in-app purchases: Guitar Chords at none against D9 Metronome's 1. D9 Metronome's advantage is device support (4 vs 2) and iOS requirement (15.0 vs 17.0). On price and ads there is nothing between them.
