지하섬 - 실시간 지하철 하차 알림

Don't miss your disembarkation notifications on your lock screen and in your notifications, even while watching videos or doing other tasks.

Jihasum is a disembarkation notification app that continuously displays how many stops remain until your destination.

Once you start your journey, it remains visible on your lock screen and notification window from boarding to disembarking. You can check the name of the next station, the number of remaining stops, and the time remaining until arrival at a glance.

(Depending on your device, it may also be displayed as a real-time notification in the status bar at the top of the screen.)

■ Tracks your train without location permissions

Even underground where GPS signals drop, it checks "the train you are on" using public real-time data instead of your device's location.

■ Vibration notifications before disembarking

Receive disembarkation alerts via vibration one stop before your stop and upon arrival.

■ Transfers in one go

It provides seamless guidance on the transfer station and the train you need to board. It also informs you of quick transfers and quick disembarkation cars.

When you arrive at a transfer station, it automatically transitions to the next train announcement, and the sections you have passed remain intact in your journey log.

■ It’s Okay If You Miss Your Train or Change Your Mind

You can select a train from the list even if it has already departed. If you switch to "Select a Different Train" during the guidance, we will continue the guidance from your current location.

You can also change only the transfer station by selecting "Transfer at Another Station" while on the way. Since the train you are currently on remains the same, the guidance will not be interrupted.

■ Commute Notification Feature

If you register your home and work (or school) locations, your journey begins with a single commute chip on the home screen.

Tapping the commute notification for your set time will immediately open the route and train list.

■ Customize Your Platform

You can change the platform you see while waiting to your desired theme. The Underground Island Platform and Namsan Platform are provided for free, while the Summer Sea Platform and Pink Princess Platform can be used indefinitely after purchasing them just once from the store.

If you set "Platform Time" to Automatic, the platform will switch between day and night based on the actual time.

Customization is a matter of personal preference, so all guidance features are the same even without a purchase.

■ Frequently Traveled Routes

Mark your frequently used routes with a star and restart them all at once from the home screen.
