Needs a lot of work

This is not really a Tokyo guide, it is a guide to lines that operate, or cross, within the Yamanote ring (I think this app falsely describes its service). You will be lost if you are beyond that, which doesnt make sense, since Tokyo doesnt exist only within the Yamamote. No zooming map in search mode - annoying. If you are a tourist hoping to use this app, a warning! You will come home to a MONSTER cell phone bill for roaming charges. Do not use out of airplane mode if you are a tourist.
