Unlock the entire fretboard with interactive drills for every shape, position, and inversion.
Stop being limited to open chords. Every CAGED shape plays the same chord in a different fret region. Learn all five shapes and the entire fretboard becomes playable. Go from one position to anywhere on the neck.
Forget bulky barre chords that kill your hand. Triads are just three notes on three strings—tiny, moveable, efficient. Drill recognition (see a triad, name it) and recall (hear a name, find it) until theory clicks. No confusion, just muscle memory.
Stay in one fret region and switch between three different voicings. Learn smooth transitions with minimal hand movement. Drill chord changes until your fingers know where to go without thinking.
Yes. There's a built-in tutorial that gets you going in under a minute, plus dedicated learn pages covering triads, the CAGED system, and inversions. The modes range from single-triad drills in one key all the way to full CAGED recognition with random chord changes — you'll naturally move toward harder modes as things start clicking.
Not much. You don't need to read sheet music or know chord theory inside out. That said, if you have even a basic feel for intervals — knowing a major third sounds one way and a minor third another — that awareness will speed things up noticeably. It's not a requirement to start, but something worth building alongside your practice.
Two core drill modes: Recognition (you see a triad on the fretboard and name it) and Recall (you're given a chord name and find it). On top of that there's Flow mode — a hands-free loop that plays triads at a tempo you set, so you can practice while playing along on your instrument. Within each mode you can narrow it down to a single chord type, one CAGED shape, specific string sets, or open everything up to all 12 keys and all four qualities at once.
CAGED is woven into everything, not an afterthought. Triads and CAGED shapes come from the same root — every CAGED shape naturally contains a set of triads, and understanding that connection is what actually unlocks the neck. Think of it like learning pentatonic scales without pentatonic boxes: you could technically do it, but you'd be navigating blind. The app constantly shows you which CAGED shape a voicing belongs to, so the two systems reinforce each other from day one.
All four: major, minor, augmented, and diminished. You can drill each quality in isolation or mix them all together — every quality, across all 12 keys, on all four string sets.
Yes. Flow mode lets you set a tempo and loop through triads hands-free — the idea is you listen and play along at the same time. That alone is a solid workout even if you know your shapes. Turn on chord changes and it steps up considerably: the app cycles through a progression and you track the changes in real time while playing. The right tempo, chord changes, all positions — that combination is something you can keep pushing for a long time.
Progression lock mode dedicates each session to a specific chord movement — I–IV, I–V, I–IV–V, and others. The trainer picks close-voiced triads so you're learning transitions that actually make sense on the neck, not random jumps. It's the most practical mode for anyone working on rhythm guitar or learning to comp.
