GuitarBub hears every note you play and times it against the click, to the millisecond. It raises the tempo when you are clean, logs every run, and shows your speed climbing. No guessing. No plateau.

Most players practise hard and stay stuck, because nothing tells them what is actually going wrong.
A note 20 milliseconds early sounds fine to you. Played a thousand times, it is the reason fast runs fall apart.
You nudge the metronome up before the last tempo was clean, and you practise the mistakes in.
Twenty minutes of noodling feels like practice. Without a number to beat, you cannot tell if you got better.
Speed is a number. GuitarBub measures it.
Connect a guitar through any audio interface, or just use your laptop’s mic. One button, in the browser. Nothing to install.
Every note is timed: early, late, or in the pocket, in milliseconds. The rush and drag bars show it as you play.
Routines lift the tempo as you play clean. Progress graphs your best tempo day by day, so you can see the climb.
Every tool a serious practice session needs, working together, in one tab.
13 time signatures, odd meters included, 36 rhythms from eighths to quintuplets, swing, drop-out bars, three drum kits and studio-rendered woodblock, claves and bell. And it hears whether you rushed or dragged.
Every scale, chord and arpeggio across the neck, in any tuning, every note spelled correctly. Hold notes and it names the chord. Play a note and it lights up.
Chain loops with their own tempo, rhythm and length. A speed curve lifts the tempo through each one. Pause, resume, and pick up on the same bar.
Record a lick by playing it or clicking it. It plays back note by note on the neck, in groups of 3, 4, 5 or 6, at any tempo you set.
Just the neck and the beat, big, with the count flashing across the screen on every click. Readable from across the room.
Daily goals, streaks, quests, achievements, a practice calendar, and a tempo graph for every exercise. Sync it all to your account.
A minor pentatonic, box 1. Roots in red. Every lesson and phrase draws on the neck like this.
Your best clean tempo, day by day: the graph in Progress.
An example of the graph, not a promise of a result. Yours is drawn from your own practice.
Short slides that draw on the fretboard, a quick test, and drills on the metronome. Every answer is worked out by the app, so a lesson can never teach a wrong note.
Notes on the neck, scales, keys, triads, CAGED, modes, voice leading, jazz ii–V–I and classical cadences.
Intervals, chord colours, notes in a key, inversions, bass lines, sing-it-back with your mic, and Pitch Memory.
Count it, hear it, play it on the click: sixteenths, triplets, swing, syncopation, odd meters, and playing ahead of or behind the beat.
Tempo ladders for alternate, economy and hybrid picking, legato, sweeps, bends graded by pitch, and blues, rock, funk and jazz studies.
Plus a Daily Bub: five questions a day, the same for everyone.
You can play songs, you have practised for years, and clean speed stopped going up. This is the measuring tape.
Theory that lives on the fretboard, not on a page. Find any note, any scale, any chord, and know why it works.
Routines, phrases and lessons you can set up once and come back to every day, with the numbers to show what changed.
Yes. Everything on the board, every lesson, and syncing with an account, free. Open it and play.
No. Your computer’s microphone works for the lessons and the click. For timing your playing to the millisecond, a guitar plugged into any audio interface is much better: it hears only the guitar.
No. The sound from your guitar is analysed in your browser as you play, and never leaves your computer. Nothing is recorded or uploaded.
No. It runs in Chrome, Safari, Edge and Firefox. You can add it to your home screen and it works offline once it has loaded.
Yes, the whole board works on a phone. For timing with a guitar, a laptop with an interface is the best setup.
No. Everything is saved on your device. An account is optional: it keeps your routines, lessons and practice log in sync between devices.
Open GuitarBub, set the click, and find out where you really are. Then beat it.
