How do I separate sleep data from two sources?

Hey there MKH15,

We recommend using the guidance below to help with data sources in the Health app:

Here's how to see which devices and apps update specific health categories:

1. Open the Health app and tap the Browse tab. 

2. Tap a category, like Activity. If you don't see the category, swipe down to reveal the search bar, then enter a category.

3. Tap a subcategory, like Steps.

4. Scroll down, then tap Data Sources & Access. Only the sources that contribute to that data type will appear. 

Here's how to see all of your sources for the Health app:

1. Open the Health app. 

2. Tap your profile picture in the upper-right corner . 

3. Scroll down to Privacy, then tap Apps or Devices.

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

Take care!
