Every shape on the neck. None of them memorised.

A chord and scale library that shows you where shapes come from, not just where to put your fingers. For the players who learned to play without ever learning why it works.

The Fretboard screen on iPhone: a five-fret CAGED window with the notes of the shape marked on the neck, and a strip underneath showing where the window sits on the whole fretboard.

/ 01 · the point

Minor is Major with the 3rd lowered a half step.

Change the triad and the app does not just redraw it. It leaves a dashed ring where the note sat in Major, draws an arrow to where it moved, and plays you both so you hear the half step.

Turn on Walk and it shows the scale tones each of the three voices climbs through to reach the next inversion. Inversions stop being new shapes and start being the same three voices going up the neck.

/ 02 · what is in it

Four screens. Nothing you have to configure first.

Fretboard

Five frets at a time, on purpose.

CAGED boxes, one window at a time, with a strip underneath that shows where that window sits on the whole neck. Letters or degrees, your call.

Free board

Mark three notes. Get a name.

Tap any notes and the app names the chord — or the closest one, and the note you are missing. Move the whole shape with one tap and the intervals hold.

Library

Whatever you found, kept.

Save a shape off the free board and it stays, named, with the frets it lives on and where it came from.

Tuner

Cents, not colours.

±5 is in tune. Noise suppression stays off while the tuner runs, because it eats the harmonics the pitch detector needs.

Metronome

It keeps running.

The tempo sits on a shelf above the tabs and stays there while you move around the app. You never lose the click to open a chord.

Today

Nine of the last fourteen days.

Minutes, streak, and the shapes you can find without looking. Measured, not awarded — there are no badges in here.


/ 03 · ipad

The same app, more neck.

On iPad the whole neck fits in one row and the tabs become a sidebar. Turn it upright and the neck splits across two aligned rows so all fifteen frets still fit. Nothing new to learn — the same four screens with room to breathe.

The Fretboard screen on iPad: the whole fifteen-fret neck in a single row, with the four tabs running down a sidebar.
