Never miss your bus or train.

01 · Live departures

"Can I catch it?"

See the trains and buses you can actually catch.

• ·Sort by which one you'd reach first, or by earliest departure.
• ·Travel-adjusted times — every row shows when it leaves and how long the walk takes, so you don't have to do the math.
• ·Catchability at a glance — the departure time turns orange when you'll need to hustle and red when you've already missed it.
• ·Each row leads with a line-color marker — a chip on rail rows, the route number in a line-colored badge on bus rows.
• ·Filter by line, mode, or direction.
• ·Pull to refresh, or let it auto-refresh every 15 seconds.

"What's the status?"

Stratus rides with you to your stop.

From "leaving the building" through "you've reached your destination."

• ·Tap any departure to track it — it stays pinned to the top of your list.
• ·Live Activity on lock screen and Apple Watch, with a countdown in your line's color.
• ·Dynamic Island countdown at the top of your screen.
• ·Departure alarm — set your heads-up threshold and Stratus pings you that many minutes before you need to walk out the door (it does the arrival − walk − buffer math).
• ·Live ride companion — once you board, the countdown switches to "N stops to your station" on rail, or live ETA on bus.
• ·Heads-up notification before you reach your stop.

03 · Alerts

"Heads-up for delays and service interruptions."

Heads-up the moment your line is affected.

• ·Banner on your dashboard for delays, reroutes, and elevator outages on the lines you ride.
• ·Tap through to full alert detail.
• ·Per-alert dismiss — hide one you've seen; it returns if conditions change.
• ·Master toggle in Settings if you don't want the banner at all.

04 · Accessibility

Don't show me a departure where the elevator is out.

Accessibility status updates live — when an elevator goes out, Stratus knows.

• ·Accessible-stations-only filter — show only stations with working elevators.
• ·Live elevator-outage integration — when an elevator goes out, the wheelchair icon disappears from affected rows and the alert surfaces in the banner.
• ·Wheelchair icon on accessible station rows.
• ·VoiceOver coverage on every primary flow — buttons, rows, and toolbars labeled and hinted.
• ·Dynamic Type up to extra-extra-extra-large.
• ·Reduce Transparency and Increase Contrast supported.
• ·Haptics respect Silent Mode and Reduce Motion.
