Meta's Muse personal AI agent comes to smartwatches: iOS version 15.0 adds an Apple Watch companion app for text, dictation, and calls, with Wear OS support too

Core Background and Industry Pain Points

Muse is Meta's personal AI agent. It launched in North America in September and reached markets such as Singapore and Japan in October. With the user's approval it handles email, calendars, restaurant bookings, shopping, and deal hunting, keeps working after the app is closed, and sends a notification when it needs approval. The friction is that during long tasks users have to pull out their phone to check progress and tap approve. On November 9, Meta's official @Muse account announced "Works around the clock, and now on your wrist": Muse is now on Apple Watch and Wear OS.

Architecture Highlights and Underlying Mechanisms

The Apple Watch version is not a standalone app; it is a companion app that ships with version 15.0 of the iOS app (per the App Store release notes), so the actual work still runs in the cloud and on the iPhone while the watch handles input and viewing. Opening it shows Meta's yeti-like character in the center, with three options: type, dictate, or call. A watch-face complication opens it in one tap. MacRumors notes the watch design resembles Muse Charm, the pocket device Meta announced in September. Wear OS is supported too, but Meta has not published a model list or minimum OS version.

Authoritative Benchmarks and Measured Results

This is a new surface for the product, not a model update; Meta has not published latency or battery figures. Public numbers available: the US App Store page lists a 4.8 rating from about 504K ratings and #1 in Productivity, and the official announcement drew about 3,500 likes. Meta has not said how much works without an iPhone nearby or whether approvals can be completed on the watch.

Developer Playbook and Getting Started

On iPhone, update Muse to 15.0, confirm it is installed on the watch in the iPhone Watch app, then add the Muse complication to your main watch face. Wear OS users should check what Google Play shows for their device. Muse connects to email, calendars, and even finance apps, and AppleInsider has warned about the privacy risk, so grant only the data you need. For teams building agent products, the split of "the phone runs the task, the watch approves it" is worth studying: long tasks need a low-interruption confirmation point more than a bigger screen.
