Does the Apple Health app use cellular data?

If you are worried that your Health app is sucking up your cellular data you can see a breakdown of your cellular usage by navigating to Settings > Cellular and scrolling down to the "Cellular Data Usage" section. From here you can see all the apps that are using cellular data and how much each app is using. If you scroll down even further to the bottom you can then tap the System Service tab for a breakdown of the built-in services that use data.
