Too big for full ipad...
This app has almost all of the features i could imagine wanting: Great sound (and nice selection of alternates), transposition, double decker or sliding keyboard, label or not, etc. My only problem is that the single sliding keyboard, which id prefer to use, is monstrously, space-wastingly large on the full-size iPad, and theres no way to scale down the key size (or if there is, its well hidden). That may drive me to abandon it for another piano app, and Ill be sorry to do that.
Its perfect for a phone or mini, though...
