Apple's Health App Will Now Tell You Your 'Health Age' and How Ready Your Body Is Today
A revamped Apple Health app uses Apple's on-device AI to turn your watch and phone data into a single readiness score, a biological age estimate, and personalised coaching tips.
Key points
- Apple announced a redesigned Health app alongside the Apple Watch Series 12 and Ultra 4 at its June 2025 event.
- A new "Health Age" figure compares your body's metrics, including VO2 max (a measure of cardiovascular fitness) and sleep quality, against your actual age.
- A new Longevity tab tracks sleep, movement, and heart health over time and can pull in lab results.
- Apple partnered with Quest Diagnostics to offer a 50-biomarker blood panel for $119, giving users lab data they can feed directly into the app.
- The updated app rolls out later in 2025, initially in US English only.
Apple's Health app is getting its biggest update in years. Reported first by TechCrunch AI, the redesign sits at the centre of Apple's push to turn your iPhone and Apple Watch into something closer to a personal health adviser.
The headline feature is Health Age: a single number showing whether your body is performing older or younger than you actually are. Calculated from VO2 max (how efficiently your body uses oxygen during exercise), sleep patterns, and blood-test biomarkers, it's the kind of summary your doctor has never quite handed you in one place.
What does the app actually do with all this?
Your data splits into two new sections. An Insights tab surfaces timely information first, much like a news feed for your body, and offers personalised suggestions. A Longevity tab scores your health across sleep, movement, and heart health over time.
The app can fold your lab results into its recommendations. Apple's deal with Quest Diagnostics, one of the largest US blood-testing companies, makes this practical: a 50-biomarker panel (a test measuring 50 different substances in your blood) costs $119 and feeds straight into the app. That's a notable move; lab integration has been the missing link in consumer health tracking for years.
A daily readiness score tells you how recovered your body is right now, similar to what Whoop and Garmin already offer, but built into the Apple ecosystem. On-device processing means Apple Intelligence, the company's term for AI that runs on your device rather than a remote server, handles the analysis without your raw health data leaving your phone. Tim Cook has argued that on-device approach gives Apple a durable edge, as we reported on 3 August.
Will this replace seeing a doctor?
No, and Apple isn't claiming it will. The tools are designed to flag trends and suggest adjustments, not diagnose illness. Think of it as a nudge layer: the app might notice your cardio metrics slipping and suggest adding short intervals to your morning run. It'll also walk you through movement assessments, with a trainer demonstration on screen, which could help people recovering from injury or managing age-related mobility changes.
| Feature | What it does | Data source |
|---|---|---|
| Health Age | Estimates biological vs. Actual age | Watch sensors, blood biomarkers |
| Readiness Score | Daily recovery and preparedness rating | Watch, sleep data |
| Longevity Tab | Long-term health trend tracking | Watch, iPhone, lab results |
| Quest Panel | 50-biomarker blood test | Lab, $119 out-of-pocket |
| Movement Assessment | Guided mobility check with trainer demo | Camera, watch sensors |
Common questions
Do I need an Apple Watch to use these features?
Most of the new features, especially the readiness score and Health Age, rely on data your Apple Watch collects. IPhone-only users will get limited access.
When can I use the new Health app?
Apple says the update rolls out later in 2025, starting in US English. No firm date has been given.
Is the $119 Quest blood panel covered by insurance?
Apple has not announced any insurance partnerships. At launch, the panel appears to be a direct, out-of-pocket purchase.
