1. WhatsApp has introduced a new Apple Watch companion app, allowing users to receive call notifications, read full messages, and send voice messages directly from their watch.
2. The app also supports features such as reacting to messages, viewing more chat history, clearer images, and stickers. It requires an Apple Watch Series 4 or later running watchOS 10 or later.
