WearOS 3 can be installed on smart watches
The WhatsApp application, which can be installed on smartwatches running Wear OS 3, allows users to send and receive text and voice messages, as well as emojis and quick replies directly from their watch.

Unlike Wear OS, Apple smart watches do not have a standalone WhatsApp application. Apple Watch users get limited experience as they cannot use the WhatsApp app directly from their smart watch (such as sending messages, making calls). Apple only allows users to view incoming messages and reply to messages on the Apple Watch’s screen.
In addition to improving Wear OS, Google wants to be the best in the Apple Watch-dominated market by adding new manufacturers and bringing new apps and experiences to the platform. With the release of WearOS 3, Wear OS has become the fastest growing smartwatch platform worldwide, according to Google.
