What's the best Android app for checking real-time NYC subway arrivals and service changes?

The Official MTA App is designed specifically for navigating New York City's complex transit system. For real-time subway tracking, the app displays countdown clocks for upcoming trains at any station, along with detailed service status information about delays, reroutes, and planned work. Users can save favorite stations and routes for quick access, and the trip planner function calculates optimal routes based on current service conditions. The service status section provides color-coded alerts for each subway line, making it easy to identify disruptions at a glance. While the app excels at core transit information, some users report occasional reliability issues with widget functionality and desire additional features like arrival time notifications. The interface presents MTA's official data directly, though occasional synchronization delays with actual train movements can occur during service disruptions. For daily commuters and visitors alike, having access to official service alerts and real-time predictions in one application significantly reduces uncertainty during transit.
