Fretsy: Guitar Neck Trainer

Fretsy turns aimless noodling into focused guitar practice — exercises to play, quizzes to test yourself, and lessons you can build, follow, and share.

PRACTICE EXERCISES
Tap once and Fretsy deals you a challenge — a key, a scale or arpeggio, and a string to start on — so you stop defaulting to the same three shapes and actually cover the fretboard. Every challenge plays back with real guitar samples, and an interactive neck diagram shows the shape with the root and scale tones color-coded.

28 QUIZZES, FOUR WAYS TO LEVEL UP
• Fretboard — name notes, intervals, triads, chords, CAGED shapes, inversions, and scale degrees; tap-the-neck challenges like Find the Note and Spot the Wrong Note.
• Ear Training — identify intervals, scales, and chord quality purely by sound, played on real guitar.
• Theory — key signatures, chord spelling, diatonic chords, extensions, mode parent keys, interval inversions.
• Reading — real staff notation and tablature: read tab licks, chords, and symbols.

Every quiz has three difficulty levels, remembers what you miss and brings it back until you own it, and keeps per-quiz streaks and bests. An optional timer turns any quiz into a speed drill.

LESSONS — BUILD, FOLLOW, SHARE
Pull any mix of the 28 quizzes and tailored practice runs into a lesson, then work through it as a checklist. Building and sharing lessons is completely free: a guitar teacher can hand a whole lesson to a student as a single link — no account needed on either end — and a student can build their own daily routine. Opened lessons are saved right in the app.
