Great product!


Recommended to all. It's nice to be able to save my favorite routes.

Best CTA app with best support


I've used this app for years now and it's excellent. Does a great job of taking the CTA api data and adding value with a great UI. I would have written my own app until I found this.

On top of that support is excellent! I discovered the old iPhone (5) incompatibility and reported it. Same day reply from author and fix came through from apple as quick as one can expect during the holiday season.

If you take the EL or the CTA in Chicago and don't use this app you might as well go to portillo's and ask for ketchup on your hot dog. LOL

Right On Point


I normally don't rave or write about apps, but this is a great one. The bus tracker is accurate to at least 100ft. For fun sometimes, if I see a bus nearing a stop I would check the map to see if it shows it approaching that stop, and it has been accurate 100% of the time.

The map option:
It is so refreshing to have a visual on where the buses are located on their route along with an estimated time of arrival (ETA).

Wish list:
I would only ask that the designers add an alarm (push notification) to be alerted at either 5 or 10 mins. prior to arrival.

It would also be nice to have a map of the trains, but I know this is because the trains don't have gps.

All-in-all it is the best app for the CTA I've come across. It's well worth the cost.

I always see people looking down the street for the bus, now I just look on the map and know where the bus is located :-)
