Overview
- The app is available now in the App Store for Apple Watch Series 4 and newer running at least watchOS 10, including watchOS 26.
- Users can open chats, read and reply to messages, react with emojis, and record and send voice messages directly from the watch.
- Images and stickers display on the watch, and incoming WhatsApp calls trigger on‑watch notifications showing who is calling.
- The watch app requires an active connection to the paired iPhone and does not operate standalone, even on cellular Apple Watch models.
- Setup is automatic as a companion to the iPhone app with no link code needed, and messages and calls remain protected by end‑to‑end encryption; Meta says more watch‑focused features will follow.
