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:

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.
