### 2/5 — It works as intended...but

*2017-05-18*

It works. But it's way OVERLY simplified. I, as a horn player, can't transpose with this. There's no "To F" button. But, if you played a different instrument, like trumpet or alto sax, it would work.

**Developer response:** F has been added

### 1/5 — So wrong

*2015-11-16*

This is ridiculous inaccurate. No flat key used sharps in the key signature??? This is so stupid.

**Developer response:** Tap to toggle between flats and sharps.

### 5/5 — Nothing better than an app that is plain and simple!

*2015-01-25*

Whoa! First off this app is just what I needed. These keys have never been simple to transpose! Second the app works. Third, nuff said.

### 5/5 — Great utility for every musician

*2015-01-24*

This app is what a lot of musician friends I have been waiting for and needing. So easy to use and so functional.  Transposing at your fingertips!! Great app!
