### 5/5 — Easy and Helpful

*2025-11-08*

This app is easy to use. Super quick to get you the exact chords. Cheap one time purchase to get all the keys. Fully recommend.

### 5/5 — This is super handy

*2025-07-05*

This is a very easy to use tool, but I have 1 suggestion.  When looking at the chords, the finger positions are written out in tab form.  But they’re upside down in relation to what common tabs are written.  You have eadgbe top to bottom like you’re looking at a guitar from the front, but tabs are written as if you’re looking at the guitar from the top, when you’re holding it and playing.  It’s just a simple change that could make us simple guitar players get it just a tad quicker!

**Developer response:** Thank you for downloading!  I am glad you are enjoying it!  I will take this under advisement!
