Manage Health data on your iPhone, iPod touch, or Apple Watch

You can set up apps and accessories to send data to the Health app, enter data manually, and change how Health prioritizes data from those sources.

How Health handles data from multiple sources

The Health app takes similar data from different sources, like steps recorded from your iPhone and activity from your Apple Watch, and organizes it based on where it comes from. By default, Health prioritizes data in this order:

  1. Health data that you enter manually.
  2. Data from your iPhone, iPod touch, and Apple Watch. 
  3. Data from apps and Bluetooth devices.

When you add a new data source, it appears above all other apps and devices that contribute data for steps in Health. You can change the order of sources at any time

Here's how to see which sources update data for specific Health categories:

  1. Open the Health app and tap the Health Data tab.
  2. Tap a category, like Activity.
  3. Tap a data type, like Steps.
  4. Tap Data Sources & Access, then tap Edit.
  5. Touch and hold  next to a data source, then drag it up or down in the list. 
  6. To turn off a data source so that it doesn't contribute any more data for that category, tap the checkmark next to the source.
  7. Tap Done.

If multiple sources contribute the same data type, then the data source at the top will take priority over other sources. Any new apps or devices that you add go to the top of the list automatically, above your iPhone or iPod touch.
