Read full description

Learn the guitar fretboard with focused drills, interactive theory, and practical tools for understanding notes, intervals, chords, modes, progressions, rhythm, and ear training. Fretlight is built for guitarists who want real fretboard fluency: knowing where the notes are, how music theory maps onto the neck, and why the shapes you play actually work. Instead of a video course or a subscription library, Fretlight gives you a clean practice space for building the skills you use every time you pick up the guitar. Practice with targeted drills: - Note Finder: learn every note on every string - Intervals: identify the distance between notes - Chord Builder: build chords from their interval formulas - Triad Builder: practice triads and inversions across the neck - Mode ID: recognize the 7 modes by their notes - Progressions: connect chords to scale degrees and harmonic function Use built-in tools: - Fretboard Explorer: tap the neck to hear and locate notes - Rhythm Trainer: strengthen your internal clock - Ear Training: identify notes by pitch - Metronome: practice with tap tempo and time signature control Study theory visually: - Modes - Chords - Keys - Triads - Circle of Fifths - CAGED System Every reference is designed around the guitar neck, with interactive fretboard diagrams and playable examples that help theory become something you can see, hear, and use. Customize the app for the way you play: - Standard, Drop D, D Standard, Open G, Open E, and DADGAD tunings - Left-handed mode - Reversible string order - Optional string numbers - Fretboard skins - Adjustable sound type - Haptic feedback - Daily practice reminders Fretlight is for beginners building their first reliable map of the fretboard, and for intermediate players who want chords, modes, triads, and progressions to feel less abstract. Open the app, choose a drill, and build the kind of fretboard knowledge that makes practice, improvisation, songwriting, and learning songs easier.

The fretboard gets easier when you can see the small chord shapes inside it. Guitar triads is a practice app for learning triads, 6th chords, and 7th chords across the neck. Not as diagrams to stare at. As shapes you actually drill, hear, and move through in time. If you already know open chords and barre chords, this is the next layer: smaller voicings, cleaner movement, and more options when you comp, write, improvise, or learn songs by ear. Practice one chord everywhere Choose a root, chord quality, and string set. Guitar triads shows you the inversions of that chord across the neck, then cycles through them at your tempo. Use it to stop learning one grip at a time. See where the same chord lives on different string sets and in different positions. Practice chords inside a key Pick a key and work with the chords that belong together. Run the diatonic chords in order, or drill common progressions like I-IV-V, ii-V-I, I-V-vi-IV, and minor-key movements. Stay in one fret range, or move through the neck as you play. Go beyond basic triads Triads are the foundation, but the app does not stop there. Pro includes 6th chords and 7th chords, so you can practice richer voicings and start hearing how those colors fit into real progressions. Guided lessons Use short lessons to understand what you are practicing, not just where to put your fingers. Learn how triad shapes connect, how inversions work, and why the same chord can feel completely different depending on where you play it. Features • Major, minor, diminished, and augmented triads • 6th and 7th chord practice with Pro • Guided lessons — Major & Minor free, all chords with Pro • All 12 keys with Pro • Four three-string sets: 321, 432, 543, 654 • Fret-range presets from open position up to the 15th fret • Common progressions inside each key • Custom progressions with Pro • Note names or Roman numerals • Pentatonic scale overlay • Hint dots for the next shape • Full-neck chord reference • Chord playback and metronome • Adjustable BPM from 40 to 200 • Optional count-in and beat haptics Built for intermediate guitarists This is for players who are tired of the neck feeling like a set of disconnected boxes. Triads help you see the chord tones. 6th and 7th chords give you more harmonic color. Progression drills make the shapes feel musical instead of random. Practice a little every day and the neck starts to open up. Chords become nearby choices, not shapes you have to search for. Free and Pro Start free in the key of C, including guided lessons for Major and Minor triads. Guitar triads Pro includes all 12 keys, 6th chords, 7th chords, guided lessons, custom progressions, fret-range cycling, and the full Key Mode practice system.
