Hey HN,<p>I built Commuter because I was tired of switching between different apps to check arrival times for BART, Caltrain, Muni, ferries, and more. This app pulls directly from the official 511 API and aims to provide a fast, clean experience focused on real-time departures.<p>There’s no account creation, it’s free to use, and it supports every major transit provider in the Bay Area—from Napa down to San Jose. You can search, favorite lines/stops, and see live countdowns with minimal friction.<p>It’s built entirely in SwiftUI using native Apple frameworks.<p>Happy to answer questions about the API, SwiftUI quirks, or anything else. Feedback welcome!
