How to customize Health for iPhone

iOS 10's Health app is a great way to keep track of a variety of health stats, whether you're tracking activity or your sleep patterns. What's more, you can customize Health to fit your exact needs. Add calories from a meal, a quick cat nap, and much more. You can even create a medical identification card with all of your essential information in case of emergencies.

Follow this guide to find out how you can take control of Health in iOS 10.

How to add or change health data

Some data, like your step count, is automatically tracked thanks to the on-board sensors in your iPhone; other information, like your heart rate, requires an external device (like an Apple Watch) to automatically log that data. There is a third option, however: You can manually add or change your health data from the Health app itself.

  1. Launch the Health app from your Home screen.
