My ear is middle-aged...and so are my eyes!

Haven’t taken music theory since the 80s. Back then I had a near-perfect ear and 20/20 vision—not so anymore, fellow travelers! This is a really great app, as thumb-based ear training goes. But some of the chapters that precede the exercises use small, light-weight fonts and the screens can’t be stretched. So if you really need to know the three alternate names for a diminished fifth chord, you may need a magnifying glass to read the superscript.


Game Center issues

UPDATE: I like the app, but the game center will still not enable on this Ipad Air 2 or the new 9.7 I just bought yesterday. I have reinstalled the app and still the same bug. Is there any specific help to correct this issue? How do I fix this? Just reinstalled and everything.



My few complaints are minor. Add a guitar sound. The piano is quality, but I'm a guitarist and would prefer it. I'd be willing to pay an extra dollar for other instruments.

The drills are very difficult, but justifiably so. Growing your aural skills takes a long time, and no one should expect to become a master in a month. This is an app to use for years to come.

On the other hand you can create custom drills to work on where you are having difficulty. This is unlocked in the full version purchased in-app for $2.99 - a worthwhile price if you ask me.

My primary complaint is that it is not obvious that many features are locked until you purchase the full version. At first I thought it was because I had not progressed. This turned out to be true in the long run, as unlocking the full version does not open up further parts of the app other than customizable drills. To unlock those parts you must succeed on previous lessons and drills. If it does unlock more than the personal drills, it is not clear, nor am I sure that my $3 was justified as a result. The way this was done is confusing.
