Apple’s Health app is a great place to see a summary of your activity and other health data. But if you have multiple devices that are acting as sources for the same data, you may get the best results by choosing which devices are prioritized for different measurements like steps, heart rate, distance traveled, and more.

You may want to prioritize Apple Health Data sources permanently or change them based on your needs. For example, if you’re thinking of running a marathon, you may want to make an external heart rate monitor your primary data source so your Apple Watch battery lasts longer (with Power Saving Mode).

There are lots of other scenarios where prioritizing your health sources can be beneficial, especially if you know that one device in particular is the best fit for tracking a certain measurement. By default, the priority ladder is manually entered data → iPhone and Apple Watch data → Bluetooth device data.

Here’s how Apple describes health source prioritization when adding new devices or apps:

How to prioritize Apple Health sources on iPhone

  • Open the Health app on iPhone
  • Choose the Health Data tab at the bottom
  • Now choose a category like Activity, then a type of data like Steps
  • Tap Data Sources & Access, then choose Edit in the top right corner
  • Use the three-line icon to prioritize a different source (top = priority)
  • Tap Done in the top right corner

Here’s how the process looks in iOS 12:

After choosing Data Sources & Access, tap Edit in the top right corner to choose a source to prioritize by dragging it to the top of the list.

Note: If you’re running the iOS 13 beta, these steps look a bit different. Tap on a data type from the Summary screen, swipe to the bottom, and look for Data Sources & Access.
