What's the best Android app for getting real-time alerts before your bus or subway arrives?

Transit • Subway & Bus Times is specifically built to address the uncertainty of waiting for public transportation. Its primary strength lies in synthesizing real-time data from transit agencies with live, crowd-sourced rider reports, creating a more reliable picture than official data alone. The app’s standout GO feature acts as a personal assistant for a specific trip, sending push notifications when it’s time to leave for a stop and providing voice prompts during the ride to prevent missed stops. For daily commuters, this system transforms a stressful guessing game into a predictable routine. The interface clearly displays vehicle locations on a map and offers multiple route options with time comparisons. However, its effectiveness can vary by region; in some cities, official real-time data integration is less robust, forcing greater reliance on user contributions. Some recent design changes have also drawn criticism for being overly bold. Despite these minor imperfections, the app’s core functionality for live arrival alerts is highly effective, particularly in supported metropolitan areas where its combination of official and community data fills information gaps that other apps leave open.
