"We'll jump to the point here and say that we prefer Buster's UI over CTA Tracker's, hands down."
- Ars Technica

"I just picked up Buster. This is the app I've been wanting _before_ I got my iPhone."

"Buster for the iPhone is a totally awesome app. I highly recommend it if you ride any CTA buses."
- via Twitter

Buster is the quickest, easiest way to find out just how long it's going to take a Chicago bus to get you on your way. Using data provided by the CTA's bus tracker system over your iPhone's EDGE, 3G, or WiFi connection, or your iPod touch's WiFi, Buster lets you know just how long you'll be waiting to board. Want to grab a coffee but not sure if you'll miss your morning bus? Need to decide which routes to take? Don't want to stand in the rain or snow a minute longer than you have to? Buster can help.

It's the perfect app for summer in Chicago- whether you're hitting Pitchfork, Lollapalooza, the Taste, or any of the street fests, Buster can help you get there.

Buster is much quicker and easier than using the CTA bus tracker website--and we think it looks a little neater, too.

Buster also allows you to store your everyday routes for one-click access, and can help you find the closest stops using your device's GPS or WiFi location feature.

Buster currently works with ALL regularly scheduled bus routes.

Big supporter, but disappointed with latest version

Seth Bro

I found Buster early on & never looked back. Accuracy, but especially ease of use, is consistently better than any other Chicago transport map, including CTA's own.

That said, I think there've been some serious UI missteps in the latest version, particularly in regard to location features. I used to hit the Nearby button & *marvel* at how the app nailed the exact two or three bus stops I needed most right then. Since version 2.0, Nearby prompts a map view, which zooms to a wide Chicagoland area to perform the search but has less interest in ever zooming back in.

The results page you wind up with, if you get one at all (b/c it clearly chugs through a lot of geo data & often times out), is a map a square mile+ in area, peppered with dozens of identical, layered bus stop icons you must peck at randomly in order to find what you need. There are a number of other tasks that were once 2 clicks, but now spread to 3 or 4 screens.

I've struggled to imagine why these UI changes were made. Since the L's been added though, & soon Metra, I wonder if the geo search area has just been widened as a general rule, regardless of the kind of request you're making.

Anyhow, I'm rooting for you guys to address these issues. I do not want to switch apps, but have honestly been considering it.

Best CTA app!


I've just about tried them all, and this is the easiest and most accurate. Never seems to get lost in space while searching, unlike a few others. I only have one beef--when I look up the routes, the stops are not listed in order. They are listed alphabetically. As I never know the exact stop closest to a distant destination, it would be helpful to see the route as driven so I could see if the bus stopped close, and which stop that would be.

Great app


People seem to forget that the app is pulling directly from the CTA bus/train trackers so if the data is off, it's likely the fault of the CTA! I've been using this app every day for well over 2 years and find it super useful. I just wish you could favorite the train stops. I noticed a star function but doesn't seem to do anything. Like a reviewer further down, I also want to toggle between Belmont & Fullerton when deciding where to transfer from red to brown in the morning.
