The Apple Health app on iPhone is a powerful way to track all facets of your health. It records data from your Apple Watch, imports records from doctors, and integrates with third‑party apps. Whether you want steps, heart rate, resting heart rate, or more, Health consolidates everything in one place.

Beyond the watch, accessories like the Withings BPM Connect ($219) and the OMRON Evolv let you log blood pressure, while smart scales such as the Withings Body Smart Scale, the Wyze Scale Ultra under $50, and the Wyze Smart Scale X Butterfly under $33 add weight and body‑composition data. Smart rings like the Oura Ring and Ultrahuman Ring, and bands like WHOOP, also feed metrics into Health.

You can rearrange the layout by tapping Edit and dragging metrics to the top—common choices include step count, heart rate, Sleep Score, blood oxygen, weight, and blood pressure. Managing data sources lets you prioritize which apps write specific data, preventing duplicates. Health also surfaces Trends and Highlights, lets you set up a Medical ID for emergency sharing, and supports sharing selected metrics with doctors or family.

Finally, third‑party apps such as Pedometer+, Cardio Bot, Food Noms, Alyx Caffeine Tracker, and Water Minder add niche data. By centralizing all this information, Apple Health eliminates the need to juggle multiple apps, giving you a daily snapshot of your wellness progress.
