I never rate apps, but my first experience with the CBC app on Feb 2016, was so good I felt I had to.
After reading some of the poor reviews (most of which are iPad), I gave it a shot anyway.
I have an iPhone 5S running iOS 9.
First, the news feed on the home screen is great, just like BBC and CTV apps used to be.
As far as streaming live radio, I allowed the app to access my location and it grabbed the local Kelowna stream right away. I then went for a walk with my dog and moved from Wifi to LTE and back again without a single hiccup.
I generally stream CBC via Chrome on my PC, now I can take the live show mobile! Great job CBC!
