Why are my calories in Activity different than the calories I see in the app?
Some apps use a different calorie model than Apple (e.g. Orange Zones) - this means that the calories in Activity might be different than what you see after ending a workout. To fix this, follow the instructions below:
Step 1: Open the Health app on your phone
Step 2: Click the Browse tab
Step 3: Click Activity
Step 4: Select Active Energy
Step 5: Select Data Sources & Access
Step 6: Scroll down to the Data Sources list and move the app to the top of the list
