Useful but seedy, time limited, and buggy

While Google Maps offer an improved experience in that regard. Hyperdia has more information available regarding JR lines/Shinkansen.
But it is limited to 30 days of free usage, there’s work around though. Also the app crashes, or made my iphone crash when I went back to the app on a previously selected travel but this time no wifi available; I worked around this by making screens its.
