Obviously, the tiny screen is a disadvantage, but the sound quality is good, and it’s handy for those times you cannot sit glued to your desktop or laptop. Generally I am happy with this app (it’s free, so it’s hard to complain too much!) However, currently, on my iPhone app, the image does not shift when I turn the phone to watch in landscape aspect—it stays in tiny letterboxed portrait. This may be an iOS 7 glitch, since it worked before the update. (Is that a familiar song, or no?) This is not as big a deal with instrumental concerts, but it absolutely suc is a pain in the neck when trying to watch an opera.
