Its almost the perfect package.

There are three things I would like to see on this program:
1-Chord inversions
2-Chord progressions (with inverted chords)
3-Option to try and identify intervals using the upper note as the root. (thats kind of trivial in use guess)
But those are the three things keeping this from being perfect. I paid $70-80 for Practice Musica and with those additions (especially the first two) itd be essentially the same program.
Amazing value, Ive had this app since release and I use it at least a few times a week.

If youre unfamiliar with the program heres what it offers:
Ear Training for intervals, chords, scales, pitches, tempos, and key signatures (thats more of a music theory exercise rather than an ear training one). You can manually type in the interval, pitch, chord, or scale by turning the iPod/iPhone sideways and inputing it one the piano (only viewable when turned sideways). Otherwise, when holding it straight up a list of options appears. For example, you can choose to input that the interval was a minor sixth rather than playing it on the virtual piano.
Also there are set difficulty adjustments or you can manually pick which ones you want on. So, if youre having trouble identifying an augmented chord form a diminished chord adjust the settings so that only augmented and diminished chords are played. You can also choose the range of notes you want to have those examples played in (theres at least 4 or 5 octaves with the lower octaves being harder to identify which, in this case, is a software/piano quality issue. But its forgivable when you see how much of the range is very audible.
Last, you can keep tabs on your overall rights and wrongs. Which examples (i.e. which specific intervals, chords, key signatures...) you identify more often than others and how often you get a specific category (i.e. intervals, chords...) right vs. wrong. So, theres enough stat tracking to keep you informed of your progress.
A well rounded package that should be on any musicians iPod, no question.
