About this app

Wondering if there are stairs right outside your subway door?
DoTheG shows you the best car and door for your station and direction at a glance.
Check transfer routes, optimal transfer spots, and estimated travel times. Save your favorite stations for quick access.
Subway location data is stored offline, so you can check it even in underground areas with no signal.

Are you tired of walking from one end of the subway platform to the other, searching for stairs or an elevator after you get off?

DoTheG is your smart subway exit and transfer guide, telling you in advance which car and door are closest to stairs, elevators, or escalators at your destination station.
Simply select the station name and direction of travel, and DoTheG will display easy-to-understand information like “5th car, 1st door,” allowing you to quickly see the recommended location on a train diagram.

On your daily commute, even a few minutes can make a big difference.
Knowing where to exit before you board can save you time wandering on crowded platforms and help you reach stairs or elevators faster.
Even when visiting an unfamiliar station, check in advance which car to wait in.

[Key Features]
• Quick Exit Locations by Station & Direction
Search for your destination station and select your direction of travel to find the car and door closest to stairs, elevators, or escalators.

• Train Diagram at a Glance
The app highlights recommended cars on a train diagram tailored to the length of each line's train formation.
No need to memorize numbers; intuitively understand your current position and the car to move to.

• Transfer Routes & Estimated Travel Time
Select your departure and arrival stations to calculate the lines to use, transfer stations, number of stops, and estimated travel time.
For supported sections, you can also check the best car/door for exiting and the ideal position for transferring.

• Favorite Frequently Used Stations
Save your commute station, stations near school, or frequently visited places to quickly open them without searching.

• Offline Subway Data
Exit location and route data are built into the app.
Since it doesn't continuously call Seoul Metro or KRIC public data APIs during operation, you can check saved information even in underground sections with unstable communication.

• Multilingual Support
Supports Korean, English, Japanese, Simplified Chinese, and Traditional Chinese.

[Supported Data]
DoTheG contains information for 344 stations and 2,572 exit locations across Seoul Metropolitan Subway Lines 1-8.
It utilizes Seoul Metro's quick exit information and the Railway Industry Information Center (KRIC)'s station-specific adjacent elevator car number information. Guidance may be limited for some stations where public data is not provided.
KRIC-provided Korail section information may only include elevator-adjacent locations.

[Please Check Before Use]
• The guidance locations are based on publicly available data and may differ from actual locations due to on-site construction, facility inspections, train formation, or operational conditions.
• The app guides you to the car/door closest to platform mobility facilities and does not provide routes by exit number.
• Transfer and travel time information may include estimations using average values.
• For your safety, avoid continuously looking at your phone while moving, and prioritize checking on-site guidance at stations and platforms.
• DoTheG is not an official app of Seoul Metro, Korail, or the Railway Industry Information Center.
