McDonald’s, Nike, Sony Pictures and State Farm are “launch partners” for Pandora’s sponsored “tips and information” inside the redesigned mobile apps. The iOS update is available now in the Apple App Store, while the Android version will be available in Google Play “in the coming weeks,” the company said.
