I have this app and Ekitan---all Japanese version----installed on my phone. And I use the Ekitan all Japanese even though I have to ask the person next to me to read kanji. The Ekitan tells me quickly. It accepts the station name spellings that I type in. This one does not. And this one does not understand my Southern USA accent so I cannot use voice. Buy Ekitan! All Japanese! Its cheaper and much better for gaijin!
