One best sources for LA’s news

The KNBC News app is a great source for local, national and world news. It’s easy to navigate and has all the pertinent local news. You can also watch the news broadcasts live through the app if they’re on the air. If you’re into pursuits, they provide great coverage and continues the coverage even after the live telecast goes off the air.

Informative and easy to use

Love this news app. It presents the current information easily and clearly, so if I’m short on time I can just grab the basics. If I have more time, I can read the story in depth. Like their coverage too usually. It is presented more neutrally (less political slanting) than the other big news outlets in the L.A. area.

Ok App

I try & stay up to date with what is happening since I live in Northern California & my elderly mother & many relatives live in LA. When you look at the top stories & each story is duplicated 2 & 3 times & this is ridiculous!!! This app used to be so much better!!! Do you just don’t care any more??? This whole app, except for the weather, has declined with the number of stories getting smaller & staying on the app longer. I get more info on Twitter from ABC La!!! Wake up & start caring because we do!!!!!!
