# How to use the Siri, Find My and Readiness apps in watchOS 27

*Readiness only works on Apple Watch Series 12 and Ultra 4, and needs at least 7 of the past 49 nights of sleep data.*

**Key points**

- The Siri app lets you revisit or start conversations, synced across Apple devices with iCloud.
- Find My is now one app for People, Devices and Items with a map-centric interface.
- Readiness on Series 12 and Ultra 4 scores activity, vitals and sleep from 0 to 10.

watchOS 27, released in September, added three apps to Apple Watch that are easy to miss among the bigger Siri AI changes: a dedicated Siri app, a single Find My app and, on the newest models, Readiness. Here is what each one does and how to get started, based on Apple’s [watchOS 27 release notes](https://support.apple.com/en-us/149077) and [Apple Watch User Guide](https://support.apple.com/guide/watch/readiness-flx4gnzby346/watchos).

## Siri app: pick up an old conversation

The Siri app gives you a place to revisit an existing conversation or start a new one. Apple says conversations sync privately across your Apple products with iCloud. For quicker access, the new Siri Modular watch face has a Siri complication, plus a rectangular complication that mirrors the top widget of the Smart Stack.

## Find My: one app instead of three

Find My is now a single app that shows People, Devices and Items with a map-centric interface. If you were used to opening separate apps to locate a friend, a lost iPhone or an AirTag, all three now live in one place.

## Readiness: a daily score from 0 to 10

Readiness is only available on Apple Watch Series 12 and Apple Watch Ultra 4, for users aged 13 and older. It gives a score from 0 to 10 based on three things: recent activity (active calories, workout effort ratings and training load), overnight vitals such as heart rate, respiratory rate, wrist temperature, heart rate variability and blood oxygen, and your recent sleep score.

The score falls into four bands: Recover (0–1), Pace Yourself (2–4), Ready (5–7) and Go For It (8–10). It updates through the day based on calories burned, naps and your daytime heart rate.

To see it, open the Readiness app and tap the Activity, Vitals and Sleep buttons for more detail. The same score is shown on iPhone in the Fitness app under Readiness, near the bottom of the screen.

## Why you might not see a score yet

Your vitals are compared with a recent baseline, which requires sleeping with the watch on for at least 7 of the past 49 nights. If you have only just started wearing it to bed, the score will not appear straight away.

Apple also notes that Readiness does not account for factors such as existing conditions or medications, and should not be the only thing you rely on when deciding whether it is safe to exercise. Blood oxygen is not available on some Apple Watch models bought in the US on or after 18 January 2024.
