Apple has unveiled a redesigned Health app that places machine learning and new sensor data at the heart of consumer health tracking, the US technology site CNET reported. The update, announced alongside the iPhone 18 Pro models, AirPods 5 and Apple Watch Ultra 4 and Series 12, introduces a Longevity tab that estimates a user’s “health age”, an Insights section with personalised summaries, movement assessments and a partnership to offer lab tests.
What the new app will do
The Longevity tab combines data from the iPhone, Apple Watch, AirPods, clinical records and compatible third‑party apps to produce a visual overview of different areas of a user’s health and what factors are affecting long‑term wellbeing, CNET reported. The health age metric compares biological indicators with chronological age, taking into account metrics such as resting heart rate, sleep, VO2 max and heart rate variability (HRV), plus any available blood test results.
- Longevity tab: shows a user’s estimated health age versus chronological age and visualises contributors to long‑term health.
- Insights tab: uses Apple Intelligence to generate timely summaries across vitals, fitness, heart, readiness, sleep and cycle tracking, with personalised recommendations and explanatory content.
- Movement assessments: on‑device vision models on the iPhone, together with Apple Watch heart‑rate data, will measure strength, balance, flexibility, movement mechanics and VO2 max.
- Lab testing partnership: Apple is adding integrated lab test results through a collaboration with Quest Diagnostics, CNET reported.
- Apple Watch readiness score: a new readiness metric is intended to help users prepare for the day ahead.
CNET said the movement assessments run entirely on the device, which Apple presents as a privacy measure because the data need not be uploaded to cloud services for analysis. The revamped Health app will be released later this year in US English, with other languages to follow; CNET did not provide a specific date for global availability.
Devices and sensors
The Health app upgrade was announced at Apple’s event that also introduced the Health Sensing System, the new sensor suite on the Apple Watch Ultra 4 and Series 12. Apple positions these devices and the iPhone as an integrated platform that combines wearable sensors, audio devices and clinical data.
| Device | Role in Health ecosystem |
|---|---|
| iPhone 18 Pro / Pro Max | Runs redesigned Health app; on‑device vision models for movement tests |
| Apple Watch Ultra 4 / Series 12 | New sensors (Health Sensing System); provides heart‑rate, VO2 max and readiness metrics |
| AirPods 5 | Part of the ecosystem supplying audio or motion data (as reported) |
According to CNET, the Insights tab will also include a “For You” section that surfaces personalised articles and videos from Apple Health clinical experts, for example explaining LDL cholesterol or balance improvement strategies.
Context and considerations
Digital health features such as estimated biological age and predictive summaries may help users better understand lifestyle impacts on long‑term health. However, clinicians caution that consumer‑grade metrics are not diagnostic and should not replace medical assessment. The app’s reliance on multiple data sources — wearables, clinical records and third‑party apps — underscores the importance of data accuracy and interoperability.
“On‑device” processing of movement tests reduces the need for cloud uploads, Apple said, which it presents as a privacy safeguard, CNET reported.
For South African users, uptake will depend on device availability, language support and local access to integrated services such as lab testing. CNET reported the initial rollout will be in US English; Apple has not yet specified a timeline for other languages or for integration with South African healthcare providers or laboratories.
Health editors and clinicians recommend that readers consult a healthcare professional if they have concerns about heart rate, sleep, mobility or other health metrics rather than relying solely on consumer apps. Digital tools can inform conversations with clinicians but are not a substitute for medical advice or diagnostic testing conducted by qualified providers.
The redesigned Health app is part of a broader industry trend toward embedding artificial intelligence and consumer devices in everyday health tracking. Regulators, healthcare systems and professional bodies will continue to evaluate how such tools should be validated, integrated into care pathways and communicated to users to avoid misinterpretation.
