Measure your walking steadiness with your iPhone
On an iPhone 8 or later with iOS 15, you can view your walking steadiness and classification to gain insight into your risk of falling.
About Walking Steadiness
Walking Steadiness uses custom algorithms to assess your balance, stability and coordination through the built-in motion sensors on your iPhone. As you walk with your iPhone, it tracks important mobility metrics, such as walking speed, step length, double support time and walking asymmetry. These are used to determine your walking steadiness and classification.
Your walking steadiness is classified as OK, Low or Very Low. You can also choose to receive a notification if your steadiness is Low or Very Low.
If you have health sharing enabled, you can choose to share your walking steadiness data and notifications with friends or family automatically.

Set up Walking Steadiness
On your iPhone, open the Health app, then tap Summary.
Scroll to Walking Steadiness Notifications, then tap Set Up.
Follow the onscreen prompts to confirm your Health Details, find out about Walking Steadiness Levels and turn on notifications.
Tap Done.

Put your iPhone in your front pocket or in a pocket near your waist while walking. You'll receive a notification if your steadiness level is low enough to put you at risk of a fall within the next year.
