Worthless.
You know, theres more to Tokyo than the Yamanote line. This app basically covers whats inside the Yamanote Loop, but for the millions of people who live outside that area - but still in Tokyo - it is utterly worthless. I wish someone would make a REAL route planner app, in English, for those of us living in anything other than CENTRAL Tokyo. Basically JR Easts service area. Now THAT would actually be worth $0.99. Heck, more than that.
