### 5/5 — Great way to learn guitar fretboard

*2025-02-01*

Great.  Shows guitar fretboard and a string/position.  Tap the note.  Repeat till all the notes become second nature

### 5/5 — Ideal tool

*2022-10-29, version 1.2*

I have produced music using music theory picked up over many years. Ideally, I should learn the piano keyboard as that is the quickest way to enter notes into digital audio workstations that I use and I have sometimes toiled to work out which chords / notes would work best to fit my ideas within the key and how to enter them. From my first look at this app I can see it would have saved me so much time as everything I need is laid out clearly in multiple views for keyboard and guitar (which I do play). I will be using this extensively from now on.

### 5/5 — best app for guitar learning on the go

*2022-07-18, version 1.2*

nice job

### 5/5 — Valuable tool for learning theory

*2019-11-04*

Love the app and already have found it useful for learning the chords for each key and improving my ability to transpose on the fly. I use the reference chart a lot for that. It would be helpful to have a circle of fifths view also in the reference section instead of just the grid layout.

### 5/5 — Good reference app

*2019-08-29*

Great for chord and scale reference. I use it mostly for scales and changes while soloing.

### 5/5 — Great app

*2019-08-23*

I find the chords by key chart most helpful for this app when trying to learn songs by ear. The chords and scales for guitar are great too. Would love to see arpeggios here as well.
