Share settings between standalone watch and iPhone app

Is it possible to share data/settings between an iPhone app and a standalone WatchOS app? Or have the watch app connect to the iOS app to send messages if available? I know how to do it the old way, but I'm moving my Watch app to be standalone and don't see how to communicate or share settings. Thanks

Quick clarification on terminology: It sounds like what you're building is a watchOS app that can run independently of its iOS companion app. The iOS app might be installed on a companion phone, or it might not (or there might not be a companion phone, in the case of a Family Setup watch).
