Tokyo Subway Map OFFLINE

good quality picture

The app is just an image of the Tokyo subway, not necessarily a bad thing. It has a handy feature that allows you to switch between a few languages which is pretty cool. What makes this app a deal breaker is that sometimes when you open up the app, ads with sound will start to play out loud, which isn’t exactly something you want to happen when you’re on a crowded train in Tokyo.

This is basically an image of the Tokyo subway with some advertisements to help the developer with some passive income. Respect for taking the time to write the app, but I think you're better off downloading a PDF of the Tokyo Subway map to your phone. At least you won't get the advertisements. This app works if you need an offline map though.
