### 1/5 — Not very good

*2026-08-07*

Poor design and organization.

I don’t see the necessity because if you just know where notes are and chord / scale shapes you won’t have any problem finding it yourself. 

The app is also not very responsive. For something as simple as showing chords and scale shapes, it should be pretty easy to run.

**Developer response:** Hello, 

We're usually all for constructive or critical feedback, but we're having trouble understanding your points here. The app has zero loading components and all screens render instantly. Also, a user that knows where every note, scale and chord shape is wouldn't need this app. This is a reference tool to help all guitarists. Thank you.

### 5/5 — Fantastic

*2026-07-28*

This is the most useful tool i have ever had, i've wasted probably no less than 400 dollars on courses searching for this

### 3/5 — Needs a left handed mode

*2026-07-27*

Needs a left handed mode

### 5/5 — Well Done!

*2026-06-30*

This is simple program that will speed up learning guitar. It’s fun comprehensive, and pushes you. Enjoy the fun !

### 4/5 — Almost Great

*2026-06-30*

I’ve enjoyed this app so far, but it seems that there is a bug in the beginner string drill where sharp notes are played but there’s no option to select a sharp. This doesn’t seem to be an issue in the other beginner modes.

**Developer response:** Hi,

I'm sorry you experienced this. I just verified that this is indeed a valid bug. I'm pushing a fix for this right away that should be available within the next day.

### 4/5 — Practice needs work

*2026-06-22*

Tried the “name the note” practice at beginner level. I’m an advanced intermediate level player and got all the notes correct but the app says I got 90%. I tried at least 5 times so there is a counting error somewhere in the code that is causing an error.

**Developer response:** Hi,

Thanks for taking the time to report this and for testing it 5 times to confirm it wasn't a fluke. You found a real bug. The scoring on a perfect round was off by one (10/10 was reporting as 9/10 = 90%). It's fixed in the next update. Sorry for the headache!

### 5/5 — Game changer

*2026-06-16*

So I had a couple hours to kill and really explored the app. There isn’t anything that this app can’t show you. Extremely informative. Pro version is an absolute must 🤘🏽

### 4/5 — Get it

*2026-06-05*

Been playing for 20+ years, and while I’m no pro, I’ve bounced around my share of apps. After less than a minute in this app the lifetime purchase was a no brainer. My only issue so far is not being able to change tunings…tapping the button does nothing. Custom tunings would be a great add.

### 5/5 — Amazing features!!!

*2026-04-08*

This app has all you would want if you are a guitar player. From novice to expert this app will guide you through everything!
