NYC Subway HUD is a lightweight subway companion for Meta Ray-Ban Display glasses. The app uses the wearer’s location to show nearby New York City subway stations, then lets the user select a station to view upcoming trains. It supports real-time MTA arrival data when available, with scheduled fallback data when a live feed is unavailable. For a selected station, users can also open a dedicated service alerts view to check current MTA delays, reduced service, no-service notices, and other station or route-related alerts. The interface is designed specifically for the 600 x 600 Meta Ray-Ban Display viewport. It uses large readable text, high-contrast route badges, focused list navigation, and works entirely with directional swipes and Enter. No touch screen, mouse, keyboard, or text input is required.
