### 5/5 — Real-world skills

*2025-04-20*

There are no other apps I could find that test tuning within chords and scales – a much more important skill than discrimination between two versions of the same pitch, which many intonation apps are limited to. I hope this remains in development as it’s really useful.

### 5/5 — If you play in an ensemble, you need this.

*2021-07-22*

This app is wonderful for ear training! If you play in any kind of ensemble, the art of listening and adjusting accordingly is crucial, and no other app is this in-depth and practical. 10/10!!!

### 5/5 — Serious Ear Training

*2021-01-24*
