The app is a very good and comprehensive app. Its my favorite so far. My only suggestion is to change the pictures of some of the coffees. I know that they are pictured (and often served) in white cups, but sometimes a layer of water ends up looking like milk because of the white cup. Of course you can tap on it and it shows you what each layer contains, but it would be more pleasing to the eye to see these in a clear glass rather than a white cup, so you can appreciate the various layers better (for example as seen in some of the specialty coffees towards the end of the list in the app, like in the Vienna coffee).
