IIACommute is a free Android app developed by Whitemetal, designed for commuters who frequently use the shuttle bus service to and from Incheon International Airport. The app allows users to check the timetable of the Airport Shuttle Bus instead of carrying a printed schedule. Additionally, it shows the closest bus stop and the estimated arrival time based on the user's current location.

With the IIACommute app, users can easily add a widget to their home screen to check the bus arrival time at a glance. The app also provides a map view of the bus stops for users to plan their journey more effectively.

The app requires two optional permissions: location and photo/media/file access. The location permission is used to provide location-based services, while the photo/media/file access permission is used for caching Google Maps data.

Please note that the app is currently not integrated with the airport railroad timetable, but the developer plans to add this feature in the future.
