Great app to use when visiting Tokyo.
Worst app ever....
Be aware that "Tokyo Metro" is just one of many companies running train services in Tokyo! Hypocritically they have included JR's Yamanote line, but not other very important lines, I can only assume because too many people would notice it missing. So to get from Shin-Okubo to Nakano, this app will recommend a route costing twice what is needed and taking a few minutes longer, without any advantages.
Don't try and go to Okubo station, as for some reason no one here thought to link the Chuo line to your journey! so many stations that you could potentially use to travel with are not visible leaving a tourist to believe you have no easy way to get to certain locations that in fact, have very easy efficient routes. App feels very illogical and times can be misleading
Estimated only 14 minutes ride between Shinjuku to Ueno but in fact took double the time! Nearly missed the Skyliner to airport! Terrible terrible terrible! Don't rely on this app for suggested route and estimated travel time! Also no detailed route info e.g. intermediary stations, making it extremely inflexible in case if a change of plan is needed. There are far better apps than this one. Disappointing app!
As a foreigner I was worried about navigating the labyrinth of Tokyo metro system, but this helped a lot especially route planner option.
Pathetic app don't waste time and data to download it. Designer of this app needs to really understand the user experience and then design. I hope that the app is designed consodering tourists. Lacks in features such as basic route planning.
Doesn't have ability to filter out connections if you have only Tokyo Metro day-pass, for instance.
