Q: Measure Calorie Burn when using workout
Hi There
The question I have is will your apple watch measure a different calorie burn rate for walking the same distance in the same time when doing so using the workout app as opposed to not using the workout app?
The reason for the question is that I read by using the workout app, apple watch switches on the relevant sensors. Does this mean that these additional motions sensors are normally off and if so would that affect the accuracy of measuring calories burnt during an exercise?
Regards
iPhone SE, iOS 9.3.2

Hi
Yes - tracking an Outdoor Walk, for example, via the Workout app may result in a more accurate estimation of your Active Calories burned during that activity.
When you track an activity using the Workout app and specify an activity type, your watch uses the most appropriate sensors and data sources to estimate the results of that workout.
For example, when recording an Outdoor Walk:
- If you also take your iPhone along (with Location Services and Bluetooth enabled), your watch can access GPS data from the iPhone when estimating pace and distance.
- If you do not take your iPhone along, the watch relies on data from the built-in accelerometer when estimating pace and distance.
- Data from the heart rate sensor is used when estimating Active Calories, including calculations that are tailored to that specified activity type.
Calibrating your watch also helps to improve the accuracy of various estimations made by the Activity app and Workout app. More information and instructions for calibrating your watch (including for resetting any existing calibration data and starting afresh) are available via the link below. Estimations of results also depend on your personal information. To check that this is accurate - and to update it over time:
- On your iPhone, in the Watch app, go to: My Watch tab > Health > Edit - tap and adjust items, then tap on Done.
