Guitar Genius is everything you need to become the guitarist you want to be. Build a practice habit that sticks, finally understand the fretboard, learn and perfect the songs you love, master your solos, and keep every tool you need in one beautiful app.
Practice can feel like a chore, or it can be the best part of your day. Guitar Genius makes it the second: clear, guided, and built to move you forward, whether you picked up a guitar last week or years ago.
SEE THE WHOLE FRETBOARD
The Scale Visualizer shows any scale in any key, anywhere on the neck. Toggle notes, intervals, or degrees, hear it played, and finally see how it all connects. Explore keys, modes, and the circle of fifths to understand the music you play.
EVERY CHORD, EVERYWHERE
Browse a huge chord library with every shape in all five CAGED positions, plus arpeggios and richer voicings. Forgot a shape? Chord ID names any chord from the frets you are holding.
PRACTICE THAT STICKS
Guided scale and chord drills on a fretboard that always shows the whole neck and slides between positions, so you never lose the context. A bright beacon shows the exact note to play next, and a preview tells you where you are heading before you get there.
TRAIN YOUR EAR AND YOUR THEORY
Sharpen your ear with interval and chord recognition, test your knowledge with a quick theory quiz, and master every note on the neck with the fretboard trainer.
LEARN YOUR FAVORITE SONGS
Loop any tricky section, slow it down without changing the pitch, and keep your own notes, tabs, and chords right beside the player. Works with your music and with YouTube.
JAM AND SOLO
When you want to just play, loop a chord progression and solo over a backing band with the scales that fit lit up on the neck.
THE ESSENTIALS, DONE RIGHT
A fast, accurate tuner with alternate tunings, a rock solid metronome, and a Speed Trainer that ramps the tempo to push your limits.
BUILT TO KEEP YOU GOING
Track your practice streak, follow guided paths, and get a daily nudge, so a little practice every day adds up to real progress.
Beautiful, fast, and made by a small team who play guitar too. Download Guitar Genius and make practice the best part of your day.
Some advanced features are available with Guitar Genius Pro.

This update makes Guitar Genius a much smaller download, and fixes an issue where returning players were sometimes asked to set everything up again from scratch.
Updating from an older version? Guitar Time is now Guitar Genius! Same app you love, a brand new name, and by far our biggest update ever, a complete reimagining of how you practice, learn, and play.
NEW: A whole music theory suite
Scale Visualizer, Key Explorer, Circle of Fifths, and a Theory Quiz. See any scale anywhere on the neck and finally understand how it all connects.
NEW: Bigger chord library and Chord ID
Every chord in all five CAGED positions, plus arpeggios and voicings. Tap the frets you are holding and we will name the chord.
NEW: Ear Training
Recognize intervals and chord types by ear, the single best skill for playing by ear.
REDESIGNED: Practice
A full sliding fretboard that keeps you in context, a bright beacon for the note to play, and a preview of the next position. Now with landscape support.
RICHER SOUND
Real sampled guitar throughout, so everything you play sounds warm and natural.
Also new: a Jam Room for looping a chord progression and soloing over a backing band.
Plus a fresh new look across the whole app, a redesigned song player with part looping, and countless refinements. Thank you for playing. We would love to hear what you think.
