Stratus - Live Chicago Transit

Never miss your bus or train. Live CTA and Metra departures with travel time, lock screen Live Activities, departure alarms, real-time alerts. Ad-free, no account.

Stratus powers your CTA and Metra commute with live data and a privacy-first approach. Built by a Chicago commuter, bus-first, because most rides aren't on the train.

LIVE CTA AND METRA DEPARTURES NEAR YOU • Buses and trains leaving from stations within a configurable travel time. Sort by distance or earliest departure. • Your favorite routes are always surfaced at the top of the list. • Every row shows upcoming departure times and how long it takes you to get there, so you don't have to do the math. • Color-coded times to flag departures that are tight vs. comfortable. • Pull to refresh, or let it auto-refresh. • Filter by route, transit mode, or whether you can still catch it.

IN-TRIP RIDE COMPANION • Tap any departure to start a trip, and track its progress on a live map with the stops you have left. • Tap any upcoming stop to see its live departures and those nearby. • Share your live ETA* so others can track the progress of your trip. • Live Activities* provide a countdown to departure on your lock screen and Apple Watch. • Configurable Departure Alarm* to notify you exactly when it's time to leave. (Premium features denoted by * )

RIDER GUIDE • A system map for CTA rail, Metra and bus, with station details, transfers, and live departures. • Fare charts for CTA and Metra, and how to pay for each. • An icon guide explaining every symbol the app uses. • Tutorials for getting started.

REAL-TIME SERVICE ALERTS • In-App banner signals when something affects a nearby route (delays, reroutes). • Tap through to view full alert detail. • Detour-aware routing in the In-Trip Ride Companion.

ACCESSIBILITY OPTIONS • Filter departures to exclude CTA and Metra rail stations without elevator access from the street to the platform. • Integration with CTA and Metra service alerts provides real-time station accessibility status. • VoiceOver coverage across the departure feed, trip tracking, and toolbars. • Supports Dynamic Type text sizing. • Haptics respect Silent Mode and Reduce Motion.

HOW STRATUS IS BUILT • Ad-free and no account required. • Your location never leaves your phone. Only CTA and Metra station identifiers are sent. • We don't track you. We only collect anonymous crash and usage telemetry. • Independently built by a Chicago commuter and not affiliated with the Chicago Transit Authority (CTA) or Metra.
