Triad Challenge
A clear route through the whole triad map.
Start with useful top-string loops, then unlock major, minor, and diminished triads across all four adjacent string sets. The app keeps the next drill obvious while your neck coverage grows.

Practice loop
See the next useful shape, not just a diagram.
After the Challenge gives you the map, progression practice turns those shapes into music: put a loop in motion, watch each chord connect to the next, and keep your hands moving in time.
Nearest playable shape
The focused CAGED triad stays close, so chord changes become fretboard paths.
Chord Explorer and All triads
Open one chord in Explorer, or tap All triads to overlay every inversion in practice.
Frets, strings, and playback
Choose the strings and fret range in play, step manually, loop at BPM, add metronome, or use optional voice commands.
What you can practice
Enough control to make the drill yours.
Start from real loops
Built-in pop, jazz, blues, and classic progressions give you something musical to practice right away.
Build your own workout
Make custom progressions, save sessions locally, transpose keys, set a capo, and choose the strings and fret range you want to study.
Stay focused on triads
Major, minor, and diminished triads, root position, first inversion, second inversion, Chord Explorer for one-chord maps, and focused practice that stays out of the way.

Questions
Built for focused triad practice.
The short version: it is a progression trainer for triads, not another folder of static shape diagrams.
What is Guitar Triad Trainer?
Guitar Triad Trainer is an iPhone, iPad, and Android app for learning triads across the neck. Triad Challenge gives you a guided route through the fretboard, progression practice turns those shapes into musical loops, and Chord Explorer helps you map one chord at a time.
What is Triad Challenge?
Triad Challenge is a 7-stage guided path through major, minor, and diminished triads across four adjacent string sets. It starts with practical top-string loops, then keeps unlocking new windows until the full neck map is covered.
How does the nearest-shape practice work?
Choose a built-in progression or make your own loop. As the chords move, the app focuses a nearby playable CAGED triad and previews what is coming next, so practice feels connected instead of random.
Do I need to know CAGED first?
You do not need to be an expert, but the app is built around CAGED triad shapes. It is best for players who know basic chords and want to understand the fretboard more deeply.
What triads can I practice?
The app covers major, minor, and diminished triads in root position, first inversion, and second inversion. You can choose the strings and frets in play, transpose, use a capo, skip open-string shapes, tap All triads to overlay every inversion in practice, or use Chord Explorer to map one chord.
Can I practice hands-free?
Yes. Optional voice controls let you say next, back, play, pause, or stop during practice. Microphone and speech recognition are only used when Voice mode is on.
Can I use my own progressions?
Yes. You can start with built-in loops like pop, jazz, blues, and classic progressions, or build and save custom triad drills from the chords you want to practice.
Can I name saved practice sessions?
Yes. Name a custom practice from the builder's Options panel, then rename it later from the Library edit button. See the naming FAQ for screenshots.
Do I have to subscribe?
No. The monthly plan starts with 7 days free, then renews at $0.99/month unless canceled. You can also choose the one-time lifetime unlock. No ads or cloud sync.
