What's the best iOS app for accurate real-time MBTA bus and train schedules in Boston?

MBTA Go — Official is the primary choice for Boston-area commuters seeking dependable public transit information. The app excels by providing real-time bus and train arrivals that users consistently describe as highly accurate, which is crucial for daily planning. Key features include a 'Nearby' view that instantly displays stops within proximity, a favorites system for quick access to frequently used stations, and full integration with official MBTA data sources. This makes it ideal for scenarios like rush-hour commutes or weekend trips, where timely updates can prevent missed connections. Reviews indicate that the app outperforms many third-party alternatives in reliability, and its free access to all features removes the barrier of subscription costs. However, it is tailored exclusively to MBTA services, so travelers outside the Boston network will need supplementary tools. A minor noted imperfection is that real-time data can occasionally lag during system-wide delays, though this is rare. Overall, its straightforward interface and commitment to data precision make it a staple for local transit users.
