Read full descriptionHide full description
DokoDemo Transit Board turns your train ride in Japan into a large, easy-to-read railway display. The interface is available in English while railway and station names remain in Japanese as provided by the source data. TRAINS The app uses your current location to identify the railway line and show the current or next station on your device. When a line or station cannot be confirmed, it shows only the information it can verify. MAKE THE BOARD YOURS Arrange board components and adjust the station count, kana, clock, and more. The one-time Customization Pack adds extra themes, train icons, and accent and train body colors. Preview its designs before buying. FOR THE RIDE • Live Activities on the Lock Screen and Dynamic Island • Live Activities in the Smart Stack on a compatible Apple Watch • Optional arrival notifications when a station you registered is approaching • Portrait and landscape layouts Start a ride from Settings to keep Live Activities and arrival notifications running when you close the app. With background arrival notifications enabled, opening the app starts a ride automatically and sets its end time to one hour later. Confirmed train movement renews that time. Rides end automatically after an hour without renewal, and you can end them manually. Location and motion processing stays on your device. The app does not upload or store your location history on a server. It does not provide timetables, route planning, transfer guidance, or real-time vehicle positions.
