### 5/5 — Fun and Educational

*2021-04-11*

This app has been key in helping me to recognize key signatures, both Major and Relative minor. It used not only the traditional Treble and Bass Clef, but also Alto and Tenor. One can also practice learning how to read the notes of the Alto and Tenor clef, an important skill overlooked. It is not only educational, bit encourages practice by making it fun!

### 5/5 — V useful

*2019-03-20, version 1.04*

This includes bass, treble, alto and tenor clefs, unlike other fancier looking apps.  You can test yourself on note names and all the major and minor keys. Substance over style. Mine has suddenly turned its display round 90 degrees and won’t go back to portrait mode.

### 5/5 — User friendly

*2016-08-18, version 1.04*

Very flexible app. You can test key signatures in bass clef which can't be found in other more expensive apps. Design is a bit dated but overall it's a useful learning tool.

### 5/5 — M

*2015-05-09, version 1.03*

Note trainer works very well. It's a fantastic app which I have used to greatly improve note recognition and also to identify key signatures and their relative minors. Highly recommended.

### 3/5 — Needs a quick fix

*2015-03-11*

Minor key for treble clef says answers are wrong even when you select the correct answer.

Needs to be fixed. Assuming that happens this app is not bad
