The subway app for on-the-go: real-time train arrivals & service status at your fingertips.
Tap a station directly on an official MTA subway map to see next trains & their real-time arrival info. Underway is optimized for offline experience, helpful during long subway rides underground: map is always available for browsing, as well as the most recent data loaded from the server.
Fastest map to use. Period.
Underway is a home-grown, independent project. We believe that public transportation should be user-friendly. Underway is supported by ad revenue and by in-app purchases.…

“Not assessed” means we could not measure it. It is never a zero and never a pass.
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.

underwayWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
