Stop juggling music theory apps. Fretboard puts everything in your pocket.
Scales, chords, progressions, drum patterns, and ear training — all in one app, built for beginners, powerful enough for working musicians. No subscription. No ads. Works offline.
LEARN FASTER WITH INTERACTIVE VISUALS
See your scales and chords light up in real time on a full guitar fretboard, 4-string bass, or 88-key piano keyboard. Watch the Circle of Fifths rotate as you explore keys and modes. Tap any note — hear it instantly with realistic instrument sounds.
Music theory stops being abstract the moment you can see and hear it.
EVERYTHING YOU NEED TO BUILD YOUR THEORY FOUNDATION
Scales (50+)
Major, Natural Minor, Harmonic Minor, Melodic Minor, all 7 Modes, Pentatonic, Blues, Bebop, Whole Tone, Diminished, and rare exotic scales. Every scale in all 12 keys.
Chords (30+)
Triads, Seventh Chords, Extended (9th, 11th, 13th), Suspended, Added, Altered, and Power Chords. With inversions, note formulas, and audio playback.
Chord Progressions (50+)
The most useful progressions in Pop, Jazz, Blues, and Classical — fully playable, transposable to any key.
Drum Patterns & Rudiments
20 patterns across Rock, Jazz, Blues, and Funk. 10 essential rudiments. A 16-step beat grid you can actually play with.
Ear Training
Interval recognition, scale detection, and rhythm quizzes. Three difficulty levels with session tracking so you can see yourself improve.
GROWS WITH YOUR SKILL LEVEL
Tell Fretboard whether you're a Beginner, Intermediate, or Advanced player — and it adjusts. Beginner mode explains every term in plain English. The built-in glossary covers 45+ music theory terms so you never get stuck on jargon. As you level up, the explanations fade out and the tools take over.
BUILT FOR YOUR POCKET, NOT YOUR DESKTOP
• Dark theme with gold accents
• Favorites system for quick access
• Practice session tracking
• 100% offline — no internet required
• One-time purchase — pay once, keep it forever
If you've been putting off learning music theory, Fretboard is the place to start.
