Notes
Every note on the neck, from the string names to the frets past 12.
Learn every note on your guitar or bass, then the intervals, chords and scales built on them. One short session a day.

You know the shapes. You know the songs. But ask for a C on the A string and you start counting up from the open string.
Counting works just well enough that it never turns into knowing. Fretboard Trainer breaks the habit by asking you, again and again, until the answer is instant.
Every lesson
Learn it
Each lesson shows you the idea on the neck, lets you try it with hints, then checks what you know. A two-minute level check skips what you already know.

Every day
Practice it
One short session a day, sized to the 2, 5 or 10 minutes you have. You always know what to practice next.

Until it sticks
Keep it
The notes you miss come back just before you’d forget them, until you know them. Watch your neck fill in as every note you know lights up.

Over 60 step-by-step lessons across five skills, each built on the last.
Notes
Every note on the neck, from the string names to the frets past 12.

Daily reminders
Optional, at a time you choose.
“15 years playing and I still had to count frets to find a note. Not anymore. Wish I'd found this years ago.”
Mark“Covers band, and the bandleader calls keys mid-song. I used to freeze every time. Way better now. Still slow above the 9th fret but getting there.”
Diane“Bass player. Knew the shapes, not the notes. Walking lines make a lot more sense now 👍”
