Your next BART train — in seconds.
Live countdown, platform, and where the train actually is.
Save your commute. Open the app. See if you should run.
- Second-precision countdown — not “3 min”, 3m 29s
- Your train, not a headsign — “Civic Center · 3 stops away”
- Platform, cars, fare, arrival — glance and go
- Reverse trip — check the other direction without retyping stations
- Installable PWA — home screen on iPhone, Android, and desktop
No account. No App Store. Free.

|---|---|
| iPhone (Safari) | Open the live app → Share → Add to Home Screen |
