How it works

Three taps. Then put your phone away.

Every other transit app shows you a list and leaves the math to you. Loop Alert does the watching.

Pick your stop

Any CTA bus route or 'L' line, your stop, your direction. Or start from Stops Near Me and a map pin.

Tap the bell on your vehicle

Not "the next one." The specific bus or run number you're going to catch, straight from the live CTA feed.

Bus #8349 · Run 922

Set it to your walk

Seven minutes to the stop? Alert at seven. Loop Alert rings when the vehicle is that far out, then keeps tracking it until it arrives.

Alert ≤ 7 min

What you get

Built for the Chicago commute.

🔔

A real alarm

Sound and haptics that cut through silent mode and a pocket, using the iPhone's alarm system. Not a notification you'll swipe away.

📡

Works when the app is closed

Our server keeps watching your vehicle about every 30 seconds and pushes the alarm to your phone. Lock it, close it, make coffee.

Live Activities

Follow the countdown on your Lock Screen and in the Dynamic Island. After the alarm, it keeps counting down until the vehicle reaches your stop.

📍

Stops near me, or near a pin

Every CTA stop around you with live times, or drop a pin anywhere in the city and see the stops around that point.

👻

Ghost and delay warnings

When the CTA loses your vehicle or flags a delay, you hear about it, so a vanished bus never leaves you standing at the stop.

Saved stops

Your daily stops one tap away. Both directions, live, the moment you open the app.

8→3in one tick

Buses jump. We say so.

The CTA refreshes each vehicle's prediction about every 30 seconds. Between two updates a bus can cover a lot of ground, so a countdown can drop from 8 minutes to 3 at once, and an alert set for "5 minutes away" can ring with less warning than that.

Loop Alert tells you this in the app before you set your first alert, and it's why we say: give yourself a buffer. Pick a threshold a couple of minutes earlier than you think you need.

FAQ

Fair things to ask.

Does it really work with the app closed?

Yes. When you set an alert, our server takes over watching that vehicle and sends the alarm as a push. Your phone can be locked with the app closed. The Lock Screen Live Activity keeps counting down the whole time.

How accurate are the times?

They're the CTA's own predictions, refreshed about every 30 seconds and generally within a minute or two. Vehicles can jump several minutes between refreshes, which is why we recommend a buffer. Loop Alert is a convenience, not a guarantee.

Which buses and trains does it cover?

Every CTA bus route and all eight 'L' lines, using the CTA Bus Tracker and Train Tracker feeds. Metra and Pace aren't included.

What about my location and data?

Location is used only for Stops Near Me, only while you're using the app, and isn't stored. There's no account, no ads, and no selling of data. Anonymous usage analytics can be turned off in Settings. Privacy policy.

How do I cancel?

Settings › Apple Account › Subscriptions › Loop Alert. If you cancel during the free trial you won't be charged.

Never run for the bus again.
