### 5/5 — Better than Choraline

*2023-01-03, version 1.2.0*

This app is a miracle. My choir has improved their rehearsal and learning process ever since they started using it!

### 5/5 — This makes choral singing fun!

*2023-01-02*

I have been able to learn my parts much more at ease using 4D Sing-Along. You can slow down, change the tone from piano to organ, adjust the volume of the other parts that I don’t sing…and there is even a scoreboard that motivates you to sing the right notes at the right time. Bravo to 4D Sing-Along! Definitely recommended for those who are already familiar with other play-along / music-minus-one tools. You won’t be disappointed with 4D Sing-Along!

**Developer response:** Thank you!

### 5/5 — More superior to Cyberbass!

*2023-01-02, version 1.2.0*

It’s time for the choral folks to check this out! Not only it surpasses what many play-along websites can offer, it makes choral singing fun again!
