"an app that plays a sound and asks to name it doesn't qualify" I don't think any ear training app works that way. Any app that is based on good pedagogical practice would be training relative pitch recognition, not note naming. An app like that would only be usable by people who already have perfect pitch. Relative pitch, which is the skill most musicians cultivate, is based on recognizing the difference between pitches as well as the sound of combinations of pitches (i.e. recognizing major/minor chords), and only much later do note names come into play. Someone with a very refined sense of relative pitch can name notes, if they have a reference pitch in their head that they can compare to (and some people take that one step further by making the top or bottom of their vocal range their "reference note", or they "memorize" the first note of some piece of music they know well, so they can figure out other pitches based on where it is relative to a known note, but that can drift). Anyway, I've tried a bunch of ear training apps and I really like Perfect Ear. It is, by far, the best ear training app I've found, and it covers tons of ground.
