Google is phasing out the old generic Wear OS app that was compatible with all smartwatches running its operating system. Starting with Wear OS 3.0, every smartwatch maker will have to build their own companion app, including Google itself. That’s why you have to download a new app on your phone when setting up the new Pixel Watch. And although that app is leaps and bounds ahead of the previous Wear OS app, it still is, in my opinion, lagging behind the companion app Samsung provides for its wearables.
