### 5/5 — LOVE this app

*2024-07-13*

I am a Cantor and guitar player at church, and did masses solo for years. Now I have a young I piano player and a few singers to join in. I use some contemporary Christian songs and I only have the words and the guitar chords. I use this app to transpose to piano when I have a song that requires a capo. It works superbly!!  I’ve used this app for about 7 years+. I don’t like or use any other app.

### 5/5 — Best transposing app

*2020-05-31, version 2.0.0*

Although the design looks a little bit outdated it does the job perfectly and the easiest transposing tool I’ve ever used. I already saved a lot of time. Awesome.

It’s as simple as ABC to transpose keys.

### 1/5 — Not getting it

*2019-06-09*

What does this do besides nothing? Agreed — I can transpose faster in my head.

### 1/5 — Must be doing something wrong!

*2019-01-07*

I must be doing something wrong. Because this does nothing. You spin the wheel and then what? I can do it faster in my head

### 1/5 — Worthless
