Ferry SF

Shipped under the Jmil Swell mark, free on the App Store and Google Play.

Live schedules and vessel tracking for Golden Gate Ferry, built by a rider who wanted a faster, clearer view of the bay. Offline-friendly schedules, AIS tracking, alerts, and fleet intel for SF Bay riders.

What it does

Everything you need before you board, and while you're on the water.

Schedules

Departures for every terminal with gates, delays, and a full week cached on device for offline checks.

Live map

AIS-based vessel positions with heading-aware ship markers, predicted locations when the bay goes quiet, and vessel specs on tap.

Alerts & news

Rider alerts from the Golden Gate Ferry list plus a district news feed so service changes surface quickly.

Fleet intel

Browse the active roster (Marin, San Francisco, Sonoma, Del Norte, Mendocino, Napa, Golden Gate) with capacity and propulsion details.

Built for riders

No account required. Location stays on-device for nearest terminal and map centering, and is never uploaded to Ferry SF servers.

FerrySF Pro

Optional subscription for unlimited live map access and an ad-free Schedule tab. Free tier includes a short map preview each session.
