Fretboard King: Guitar notes
Know the fretboard, every note
Free · Designed for iPad. Not verified for macOS.
Learn every note on the fretboard - the skill that unlocks solos and ups your level.
Fretboard King drills you in fast sessions. The app names a note and a string, G on the A string. Tap where it is on the neck, or play it on your guitar and the app listens. You know instantly if you're right, and if you miss, the correct fret lights up. Round by round, you learn every note on every string. Includes learning hub for new learners.
Core value: you learn every note on the guitar neck, so scales, chords and solos start to make sense.
-Note-find drill. The app names a note and a string, and you tap where it is. You build instant recall of every note on the neck.
- Rounds of 6, 12 or 24 notes. A round fits a spare minute or a long practice session.
- Timed or untimed. Learn at your own pace, then push for speed.
- String and fret filters. You drill exactly the part of the neck you want.
- Octave game. Find one note on every string. You connect notes across the whole neck instead of learning them string by string.
- Focus sessions. One tap drills your weakest string. Practice goes where you need it most.
- Mic note detection. Play the note and the app checks it. Audio stays on your phone and is never recorded. You practise on the actual instrument, not just a screen.
- Listening card. It shows the note you're playing in real time. You know right away whether you hit the right note.
- Octave quiz on the guitar. Play a note, then its octave. Octave shapes end up in your hands.
- Built-in tuner. An in-tune guitar means the app reads your notes correctly, with no separate tuner app needed.
- 4 guided lessons: Open String Mastery, Landmark Frets, Standard Octaves, The B-String Shift. You get a step-by-step method, not just repetition.
- Fretboard Explorer. Tap a note and see it everywhere on the neck. You see the patterns across the whole neck at a glance.
- Progress sheet: accuracy trend, per-string bars, trickiest note, best streak, answer speed. You see exactly where you're improving and what to work on.
- Daily Note: one question a day, with a link straight into a round. Keeps the habit going in a few seconds a day.
- Progress nudge. It fires only when your accuracy has actually improved. It encourages you with real progress, not reminders for their own sake.

Ratings & Reviews
Small update, big fixes:
- Overtime now works properly — the unlock ad plays all the way through instead of closing early. Watch it once and the rest of your day is ad-free.
- Smarter daily note — your daily question now targets the notes you actually find hard (and no more duplicate notifications).
- Fewer interruptions: we ask about ratings and feedback far less often, and never on your first day.
- Fixed the daily reminder toggle when notifications are blocked on your phone.
Keep practicing — 8 out of 10 players measurably improve.
