Platform: NYC Subway Times

Platform is an unofficial app for the New York City subway. It is not affiliated with or endorsed by the MTA. Set the train you actually take — station, direction, the lines you would board, and the time you leave the house. Fifteen minutes before that time, a live card appears on your Lock Screen by itself with your next trains, each one counting down to the minute. Open the app and it checks the feed again, more often the closer your train gets. Fifteen minutes after you leave, the card clears itself away. REAL TIMES, NOT A TIMETABLE Arrivals come from the MTA's own live GTFS-realtime feeds, and the app tells you how old that data is. If a feed cannot be read it says so, rather than showing an empty platform and letting you think no train is coming. A scheduled time nobody is running is worse than no time at all. THE RIGHT PLATFORM All 496 stations. Four separate stations are called "Times Sq-42 St" and three are called "14 St-Union Sq" — the picker tells them apart by borough and by the lines each platform actually serves, so you never set a reminder for a platform you do not use. Direction is shown as the real destination on the front of the train, never as a raw "N" or "S". ONLY THE LINES YOU WOULD BOARD Pick N and Q but not R, and that is what you are told about. Whichever of them comes first. NO ACCOUNT, NO TRACKING There is no sign-up. Your reminders are stored on your phone. The app has no analytics, no advertising and no third-party SDKs, and the only server it talks to is the MTA's. Platform is unofficial. Train data is published by the Metropolitan Transportation Authority; service changes, delays and planned work are theirs, not ours.
