### 5/5 — Excelente App

*2025-09-13, version 3.1.1*

Excelente App

### 4/5 — Good, however…

*2023-08-20, version 3.1.1*

I’veHad the free version for quite some time. Today I decided to buy the pro version. I mean, for $.99 Who can argue? But I was interested in getting the custom instruments. As soon as I tried it, the app crashed. And that’s the only thing it does when I try to work with custom instruments. If this could be fixed, it would be five stars.

### 3/5 — Good Start

*2020-05-05*

I was looking for some help in transposing my church worship band music to play on my Euphonium and this is a good start. A few extra features would be useful; how key signatures change between keys for example.

### 5/5 — Great App!

*2019-11-16, version 2.0*

This app is very simple, and rightfully so as it simply gives the information needed to transpose. Very useful, not very large in size and good to have if you are any type of musician.

### 4/5 — Good but needs more

*2019-08-14, version 2.0*

Good app for major notes but no access to minor etc.

### 5/5 — Great App :D

*2018-10-04, version 1.0.1*

Very useful and easy to use. The customizability is very nice and intuitive.
