This is an application that provides real-time subway arrival times using public data.
If you save the station you board at to and from work, you can check it right away without having to look it up.
If you want to know the arrival time of other stations, you can check it through a separate inquiry.
You can use the dark mode and white mode according to your preference.
If you need to check the route map, you can do so by clicking the icon that takes you to the public data subway route map.
