### 5/5 — Great to find singing key transposing a song

*2024-01-09, version 1.0.1*

Quick, easy and simple. I use this when I don’t have an instrument  and on the go and need to figure out the best key to sing a song in. I do wish there was a setting for some overlap In the chords when you play them, but I can’t complain to much about a free app with no ads. Thank You!!!

### 4/5 — Works most of the time

*2022-11-06, version 1.0.1*

I love how the app works. But some times when I click a note it dose not play. I need to reload the app if this happens.
