Siri could soon know how you slept, how you trained and whether you closed your rings — just by asking. Code hidden in the first iOS 27.3 beta points to Apple preparing Siri AI to read your Health data, according to a new find by code researcher pdfu, who posted the discovery on X on November 11, 2026.
The beta contains two disabled feature flags — IF/HealthSearch and IF/HealthSnippets — that would plug the Health app into Siri AI. Both are switched off, and there is no easy way to turn them on, so nothing changes on your iPhone yet. But the code shows exactly what Apple is building towards.
Key Takeaways
- What was found: Two disabled feature flags in iOS 27.3 beta 1 — IF/HealthSearch and IF/HealthSnippets — that would let Siri AI read Health data.
- What Siri could answer: Sleep summaries, workouts, Activity rings, Readiness, medication schedules and your Health Age, drawn from 92 HealthKit data types.
- What it could show: Custom on-screen visuals for health stats, rings, workouts and sleep summaries.
- Status: Both flags are off, Apple has announced nothing, and flags like these can change or disappear before release.
- Context: The redesigned Health app returns in the iOS 27.3 beta (Nov 3), and iOS 27.3 is due for release in December 2026.
What the Two Flags Would Do
The first flag, IF/HealthSearch, adds Health to Siri AI’s “find” tool. According to pdfu, it can search recent readings and historical summaries across 92 HealthKit data types, with dedicated queries for specific areas of the Health app: Activity rings, individual workouts and workout summaries, Readiness, sleep summaries, medication schedules and logs, and Health Age and health assessments in the new Health app.
One notable omission: Vitals is not on that list, even though the redesigned Health app’s Insights tab covers vitals alongside readiness and sleep.
The second flag, IF/HealthSnippets, covers the visual side. It would let Siri answer with custom visualisations for health statistics, Activity rings, individual workouts, workout summaries and sleep summaries — so instead of just reading out a number, Siri could show you a proper chart or ring graphic.
Together, the pair would turn Siri into a conversational front end for the Health app: ask “How did I sleep?” or “Did I close my rings yesterday?” and get an answer built from your own data, with a visual to match.
The Gap This Would Fill
Right now, Siri AI cannot read Health data on your iPhone at all. Apple’s own support pages confirm the gap. Siri can read and write some Health data — such as blood pressure and body temperature — on an iPhone running iOS 17.2 or later, but only when your Siri language is English (United States) or Mandarin Chinese for mainland China.
The redesigned Health app already gathers the data Siri would need. Its Insights tab pulls together heart, sleep, readiness, fitness, vitals and cycle tracking, while the new Longevity tab analyses long-term trends and produces a Health Age estimate. The Readiness score — a number from 0 to 10 — needs an Apple Watch Series 12 or Apple Watch Ultra 4.
Apple tested this redesigned Health app in the iOS 27.2 beta, pulled it before that update shipped, and brought it back in the iOS 27.3 beta on November 3. The Health flags landing in the same beta is unlikely to be a coincidence: the new app and the Siri access look like two halves of the same plan.

Keep Expectations in Check
This is code, not a feature. The flags are disabled in beta 1, pdfu says there is no easy way to enable feature flags on iOS or watchOS, and Apple has not announced Siri AI access to Health data. Feature flags discovered in a beta can change, shrink or vanish entirely before the public release.
There is also a privacy question Apple will have to answer if this ships: health data is among the most sensitive information on a phone, and users will want to know what Siri can see, where the answers are processed and how to turn it off. pdfu also found that the same beta sends about 2% of English Siri AI requests to a local model — a small sign of the on-device direction Apple is pushing.

The Bigger Picture: Siri Is Learning to Remember
The Health flags are not the only Siri groundwork in iOS 27.3. The same beta contains the early infrastructure for a Siri “memory graph” — a system that would connect personal information across relationships, places, routines, health and workouts, so Siri could remember things about you rather than just what you said to it. That work, also found by pdfu and reported by MacRumors, is still unfinished: there is not yet a process that creates the individual “memory atoms” the system is designed around, and Apple has announced nothing.
Taken together, the picture is clear. Apple is rebuilding Siri around personal context — your health, your routines, your life — and iOS 27.3 is where the pieces are quietly coming together. Whether the Health access survives to the December release is the next thing to watch.

Frequently Asked Questions
Can Siri AI read my Health data right now?
No. Siri AI cannot read Health data on your iPhone at the moment. The iOS 27.3 beta contains two disabled feature flags (IF/HealthSearch and IF/HealthSnippets) that would enable it, but they are switched off and there is no easy way to turn them on.
What health information could Siri AI access if the flags are enabled?
According to the code find, Siri could search recent readings and historical summaries across 92 HealthKit data types, with dedicated queries for Activity rings, workouts, Readiness, sleep summaries, medication schedules and logs, and Health Age. Vitals is notably not on the list.
When will iOS 27.3 be released?
Apple has not announced an exact date, but iOS 27.3 is due for release in December 2026. The redesigned Health app is expected to arrive with it.
Do I need an Apple Watch for Siri to answer health questions?
The Health app on iPhone holds much of the data itself, but some metrics need a watch — the Readiness score, for example, requires an Apple Watch Series 12 or Apple Watch Ultra 4.
Has Apple announced Siri AI Health access?
No. Apple has not announced this feature. The discovery comes from disabled code in the iOS 27.3 beta found by researcher pdfu, and feature flags like these can change or disappear before release.
