Overview
- The watchOS app is live on the App Store and can install automatically for users with simultaneous downloads enabled or manually via the iPhone Watch app.
- Users can read and reply to messages with text or voice dictation, send and listen to voice notes, react with emojis, view images and stickers, and receive WhatsApp call notifications.
- Compatibility requires Apple Watch Series 4 or later running watchOS 10 and a linked iPhone, as the app operates as a companion rather than a standalone client.
- Meta says messages on the Apple Watch maintain end‑to‑end encryption consistent with WhatsApp’s mobile apps.
- Early hands‑on reports highlight limitations such as restricted chat list depth, questions over starting new chats, and sticker‑sending gaps, with Meta indicating more features are planned in future updates.
