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.
