NYC Underground

NYC Underground turns your iPhone into a fast, native New York City subway companion. The complete MTA subway map is bundled right into the app: pinch to zoom anywhere, tap any station, and see real-time train arrivals the instant you look.

No account, no sign-up, no ads. Your location never leaves your device.

FEATURES

• The whole subway map: the full New York City subway map is built in and renders at high resolution. Smooth pinch-to-zoom and pan, even at street level.
• Real-time arrivals: tap any station to see live train times, straight from the MTA's official real-time feeds, grouped by direction with colored line bullets.
• Your location on the map: an optional GPS dot shows exactly where you are on the subway map, so you always know which station is closest.
• Nearby stations: one tap shows the closest stations ranked by distance, each with live arrivals.
• All 445 stations: every line, every borough, with proper station complexes and direction labels sourced from official MTA data.
• Always current: arrivals refresh automatically every 30 seconds. No API key, no login, nothing to configure.

PRIVATE BY DESIGN

NYC Underground does not collect analytics, has no trackers, and requires no account. Your GPS location is used only on your device to place the dot on the map and find nearby stations; it is never transmitted anywhere. The app's only network requests are to the MTA's public real-time data feeds.

HOW IT WORKS

1. Open the app, the subway map loads instantly.
2. (Optional) Allow location to see your position and nearest stations.
3. Tap any station to see real-time arrivals by direction.
4. Tap the location banner for a ranked list of nearby stations.

REQUIREMENTS

• iPhone running iOS 18 or later.
• An internet connection for live arrival times (the map itself works offline).
