• Color-coded prediction times give you a quick scan of what's coming up:
Red: arriving within 5 minutes.
Blue: arriving between 6 ~ 10 minutes.
Grey: arriving in more than 10 minutes.

• Toggle predictions display
- Tap on bus route number/train line name to toggle whether to show vehicle ID and current distance to the stop
- Tap on prediction times to toggle ETA in minutes left, or in your local time
- Tap on the "ALL" button to toggle whether to show predictions for the selected route, or for all routes at the stop
- Tap on route destinations to toggle whether to sort predictions by ETA, or by route

• Look up predictions easily
Scroll or Search routes/directions/stops. Routes and Directions are ordered alphabetically; Stops and Favorites can be ordered either alphabetically or by distance to your current location (turn on Geolocation by tapping on the tracking icon on the top left).

• Search train stops
Type the line color (blue/brown/green/orange/pink/purple/red/yellow) or stop name to filter train stops.

• When at a bus stop
Use the "Find a Stop by Stop ID" feature and type in the stop's ID, which should be displayed on the bus routes board, to get faster access of the predictions.

• Fresh and dynamic public transit data powered by Chicago Transit Authority (CTA) tracking service
NOT static bus schedules.

• Automatic data refresh
Vehicle arrival predictions are automatically refreshed every minute, which is the minimal update interval supported by CTA's tracking service. No manual effort needed.

• Data caching
The app caches as much static information as possible, such as routes/directions/stops, to help reducing your phone's unnecessary data usage, and boost tracking speed. The cache will be automatically refreshed in reasonable intervals to keep the data fresh.

Happy predicting and riding!

Finally: an app that works perfectly

After trying a few other transit apps and continually being disappointed, transit master saved the day. I am forever grateful. Slick design, easy to use, and reliable.
