nGeneSubwayWatch

nGeneSubwayWatch brings Korean subway route planning and estimated destination tracking to iPhone and Apple Watch. Search directly on either device, compare route suggestions, review transfers and stops, and start tracking from the screen already in use. When paired devices are reachable, the latest route, selected option, settings, and active trip state are synchronized locally so the most recent action takes priority. During an active trip, the app estimates progress along the selected route and displays the estimated current station, next station, remaining route distance, and overall progress. A circular Apple Watch complication keeps the remaining distance visible at a glance, while its outer ring represents route progress and changes color according to the remaining-distance range. Destination alerts are available at 5 km, 2 km, 1 km, 500 m, 300 m, and 100 m. Each level can be enabled independently and previewed from Settings. Sound and vibration can be controlled separately, and the number of pulses increases as the destination approaches. An inactivity-based Auto Stop timer can end trip tracking after 5 minutes, 10 minutes, 30 minutes, 1 hour, or 3 hours. Opening or interacting with the app resets the countdown. Features: • Standalone Korean subway route search on Apple Watch • Route search and estimated trip tracking on iPhone • Latest-action synchronization between paired devices • Start Trip and Stop Trip controls on both devices • Estimated current station, next station, remaining distance, and route progress • Circular Apple Watch complication for remaining distance and progress • Individually configurable 5 km, 2 km, 1 km, 500 m, 300 m, and 100 m alerts • Independent sound and vibration controls with alert previews • Nearby-station discovery using device location • Korean and English interface and station search • Multiple route suggestions with transfer details • Recent trip history on iPhone and Apple Watch • Automatic trip stopping after a selected inactivity period • Local route, settings, and trip-state persistence Privacy: Route calculations are performed on-device. Location is used only for nearby-station discovery and estimated trip progress. Route, settings, and trip state may be synchronized locally between a paired iPhone and Apple Watch. No account or subscription is required, and no personal data is sent to external servers or shared with third parties. Trip position and remaining distance are estimates based on device location and the selected route, not live train-position data. GPS accuracy may be reduced underground. Apple Watch complication refresh timing is managed by watchOS.
