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

Your Health app can collect data from your iPhone, iPod touch, or Apple Watch, and also from other Bluetooth devices connected to third-party apps. If you have multiple data sources, you can prioritize how Health handles similar data (like steps or distance) from these sources.

Find out which iOS device and software you need to use the Health app.

How Health handles data from different sources

Instead of adding similar data from different sources (like the steps from your iPhone and the steps from your fitness band), Health organizes and inputs data based on where it comes from. By default, Health prioritizes data in this way:

  1. Health data that you input manually.
  2. Data from your iPhone, iPod touch, and Apple Watch. 
  3. Data from other third-party apps and Bluetooth devices.

When you add a new data source, like a new step counter app, it will appear above all other third-party apps and devices that contribute data for steps in Health. Activity App data and measurements are automatically included in the Health app breakdown. 

View your data sources

You can view all the sources that contribute data for each category in your Health app.

Open Health and tap Health Data. Choose a category, like Fitness.

 

Choose a type of data, like Steps.

 

 

Tap Share Data. Look under Data Sources. 

 

 

Depending on the type of data you select, you might see your iPhone, iPod touch, or Apple Watch, and you might also see other third-party sources. Tap to see all of the data contributed by a source.

 

Edit your data sources

You can edit and rearrange your data sources to change the way that Health prioritizes data.

On the Share Data screen, tap Edit. Then touch and hold  next to a data source. The data source that you place at the top will take priority over other sources that contribute that type of data. 

 

Move the data source up or down in the list. To turn off a data source so that it doesn't contribute any more data for that category, tap the checkmark.

 

 

After you reorder your list, any new apps or devices that you add will appear at the top of the list, above your iPhone or iPod touch by default. You can change the order of your data sources anytime.
