If you’re going to be taking trains in Japan… just get this app. This is probably my first time writing a review, but I just had to get the word out that this is legitimately a bible for travel in Japan. I did not close this app like once my whole trip! It isn’t perfect, but it’s extremely practical and I would have never gotten through Tokyo without it. It was almost entirely accurate, with only a couple cases where it left me a bit confused, and even then it’s what saved me from that confusion itself every time. Some advice: Use the screenshot feature for every route you plan. I have roaming data but it still cut out in some places so you have to have things saved to access them at any point! Also, I liked to use this in conjunction with Google Maps for the walking routes since the path from this app was a bit hard to read for me. There are plenty of other features on this app that I’m sure other reviewers will talk about, but I’m just so grateful for this app’s help with trains and I think it’s a no-brainer to install it.
