Never miss your bus or train. Every CTA bus, L train and Metra train near you, with each departure time colored by whether you can still catch it. No account, no ads.
Stratus shows every CTA bus, L train and Metra train leaving near you, with each departure time colored by whether you can still catch it. Built by a Chicago commuter. It covers buses too, 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 CTA and Metra favorites stay together 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.
• Each departure time is colored comfortable, tight or too late.
• Pull to refresh, or let it auto-refresh.
• Filter by route, transit mode, or whether you can still catch it.
FOLLOW YOUR TRIP
• 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.
