How to Use the iPhone Health App — A Plain-English Guide for Seniors

The Health app comes pre-installed on every iPhone. You do not need to download anything — it is already there. The pink heart icon lives on your home screen. Many people ignore it, but it holds useful information and one feature — Medical ID — that could help emergency responders care for you faster.

This guide walks through the most useful parts of the Health app in plain English. Some features need an Apple Watch. Others work on any iPhone.

What you do NOT need an Apple Watch for

The Health app on your iPhone alone can track:

• Steps and distance walked each day (your phone counts your steps automatically using its built-in motion sensor — no watch needed)
• Flights of stairs climbed
• Walking speed and stride length
• Headphone audio levels (it monitors if your earbuds are too loud)
• Menstrual cycle (if relevant)
• Health records from your doctor's office (some hospitals and clinics can share records directly to the app)

Your iPhone has been counting your steps silently in the background since you first set it up. Open the Health app and tap "Browse" at the bottom, then tap "Activity" to see your step history going back months.

What you DO need an Apple Watch for

An Apple Watch (any model, Series 4 or newer recommended) adds:

• Heart rate monitoring — continuous readings throughout the day
• Blood oxygen levels (Series 6 and newer)
• ECG (electrocardiogram) — a basic heart rhythm reading (Series 4 and newer)
• Irregular heart rhythm notifications
• Fall detection — the watch can call 911 automatically if you fall and do not respond
• Sleep tracking (some iPhone-only sleep tracking exists, but the watch version is much more detailed)

The four tabs explained

When you open the Health app, you see four tabs along the bottom:

*Summary:* Your personal dashboard. Shows highlights from today — steps, heart rate (if you have a watch), sleep, and anything else you've pinned as a favorite. This is the tab you'll visit most.

*Sharing:* Share your health data with a family member or doctor. If your doctor's office uses a compatible system, you can connect directly here. You can also share a summary with a trusted family member.

*Browse:* The full library of everything the app can track, organized into categories: Activity, Body Measurements, Heart, Mindfulness, Mobility, Nutrition, Respiratory, Sleep, Symptoms, Vitals, and more. Tap any category to see what is being tracked.

*Medical ID:* This tab is critically important and is explained in detail below.

How to set up your Medical ID

Medical ID stores your name, date of birth, blood type, allergies, medications, medical conditions, and emergency contacts. First responders, paramedics, and emergency room staff can read your Medical ID from your locked iPhone. They do not need your password.

To set it up: Open the Health app → tap your profile picture in the top-right corner → tap Medical ID → tap Edit (top right) → fill in your information → make sure the "Show When Locked" toggle is turned on → tap Done.

After setup, someone can read your Medical ID from a locked iPhone by going to the emergency call screen and tapping "Medical ID." This works even if your phone is locked.

Keep your medication list and emergency contacts updated here. It takes five minutes and could genuinely help in a medical emergency.

Steps tracking — what to expect

Your iPhone counts a step every time it detects the motion of walking. It is not perfectly accurate. But it is remarkably close for everyday tracking. Aim for a general sense of your activity level rather than treating the number as exact.

To see your steps: Open Health → tap Browse → tap Activity → tap Steps. You will see today's count and a bar chart of recent days. Tap "Show All Data" to see individual daily totals going back as far as your phone has been tracking.

A common goal is 7,000–10,000 steps per day, but any increase from your personal baseline is helpful. The Health app can send you a weekly summary of your activity if you turn on notifications.

Sleep tracking

On iPhone alone (no watch): Open Health → tap Browse → tap Sleep → tap "Set Up Sleep." You set a sleep goal and a schedule. The phone uses motion detection to estimate when you fell asleep and woke up. It works best when your phone is on the bed near you or charging on your nightstand.

With an Apple Watch: Wear your watch to bed (or charge it for 30 minutes before bed and put it back on). The watch tracks your sleep stages — light sleep, deep sleep, and REM sleep — and sends that data to the Health app automatically.

Sharing data with your doctor

Some health systems — including major hospital networks — let you connect your Health app directly to your patient portal. This means your doctor can see your step counts, heart rate trends, and other data you choose to share.

To check if your doctor's office supports this: Open Health → tap your profile picture → tap Health Records → search for your health system or doctor's office. If they are on the list, you can connect in a few taps.
