### 1/5 — Horror

*2017-09-20, version 1.4*

I just purchased this app write now, and it don't work, when i open it, it crashes immediately. iPad air 2. Nightmare.

### 5/5 — Brilliant

*2017-07-27, version 1.4*

All your apps are clear and concentrate on what works ! They have  been invaluable to a new improviser. Would like another on ear training please 😁

### 1/5 — Crashing on ipad3 running iOS 8.02

*2014-09-26*

I am having problems with the introduction and all 7 lessons crashing on my ipad3 running iOS 8.02 . I tap to open , but the screen just crashes back to my general iPad screen .

### 1/5 — Crash

*2014-09-23, version 1.2*

Another crashing app. Does anybody test anything? Losing faith with Apple and ITunes.
Let down far too often.

### 5/5 — Vsl

*2014-08-09*

Veyssyolla!

### 5/5 — comprehensive and practical

*2013-01-11, version 1.2*

It's hard to believe the little app does provide such comprehensive and practical info for self-learn beginners. "Note to Chord Relationships" is the best part of the app.

### 4/5 — Quantum leap improvement

*2012-11-08, version 1.2*

At the risk of sounding over the top this little app has transformed my nervous noodling into some authentic improvisational -- and all within a few hours. Looking forward to moving to the next level.

### 5/5 — Perfect app for my jazz training..

*2012-10-30*

This app is amazing (fundamentals). I was looking for different ear training apps and came across this app. I was stunned as this was everything I wanted and a TON more. The jam a long tracks are awesome. I immediately took a chance and purchased it and am glad I did. I'll be getting the ii-V version next. 
Im thinking the reviewer who stated that the app had the wrong key didn't realize that you could change the key of the app to the key of your instrument in the settings. I'm playing an alto so I changed mine from C to Eb...

### 5/5 — Bravo!

*2012-09-30*

Thanks for the prompt update; I'll be downloading all of your other iImprov apps now- and recommending them to my students, as well.

### 5/5 — Now compatible for iOS 6.

*2012-09-29*

Great so far. Better than other theory apps that I've downloaded.
