### 1/5 — App is pointless

*2023-04-24*

Don’t waste a dime on this app. It is literally two pictures of graphics & nothing more.

### 3/5 — Why no minor key functionality

*2019-11-15*

Handy for pupils but why is it limited to major tonality only?

### 1/5 — Not helpful

*2016-11-06*

It's just two graphics of the circle of fifths and another chart.  No interactivity or functionality.

### 2/5 — Can't hear the chords?

*2016-11-05*

Is this a silent music app?  Not as useful in this state.

### 1/5 — Useless, waste of money

*2015-11-21*

Not working under ios 9.1
