I am currently traveling in Japan. I tried to use Google maps and Apple maps at first but both maps didnt provide enough detailed alternatives for train rides. I have been using this train app to look at all the different trains going from Osaka to Kyoto and vice versa. I get to see and choose from super express Thunderbirds, wide view Hida, Shinkansen, or new express train. For JR pass holders, it is a no brainier to ride a more comfortable and quicker train. This invaluable train app has made my train ride decision so much easier as a foreigner in Japan. 100% recommended.
