it’s tracking my steps but not calories ?

Hey A___AAAA,

Welcome to Apple Support Communities.

The Health app gathers its information via the apps installed and devices. You can see which apps the Health app is getting data from by going to Settings > Health > Data Access & Devices. > Sources. From there, you can click each app to see what data is being updated in the Health app.

In the screenshot, it does show how may calories burned during active energy and also resting energy. This data is associated with Challenges app.

If you still have questions or need further assistance, contact Apple Support directly here: Get Support. The Health Support Advisors are the experts and will be able to help you with with this.

Take care.
