Stand
- For the purpose of crediting the hourly Stand achievement, your watch aims to identify when you have stood up and moved around for at least one minute during that hour.
- Apple Watch uses an accelerometer to identify movement, so arm movement equivalent to changing from a seated to a standing position followed by a minute's walk around with your arms swinging naturally should help to register this.
Exercise
- To credit progress towards your daily Exercise goal, the Activity app aims to identify activity that equals or exceeds the intensity of a brisk walk.
- This requirement applies both during general daily wear and when recording workouts via the Workout app.
- One minute of Exercise credit is awarded for each minute during which this requirement is met.
- The definition of a brisk walk varies from person to person and depends on your personal information.
Move
- The Move goal estimates active calories burned.
- Estimations depend on information including your movement and heart rate data recorded during any workouts.
Be sure to record any workouts using the Workout app (or a third-party fitness app that shares data to the Activity app).
Apple Watch uses different sensors and data sources to track the results of any workouts, depending on the activity type. For example, with Apple Watch (first generation) and Series 1 models, the Workout app can access GPS data from the paired iPhone if it is taken along during outdoor walking, running and cycling workouts. Series 2 has built-in GPS.
During general daily wear and when using the Workout app to record workouts when GPS data is either not relevant or not available (eg Indoor Walk), the Activity app and Workout app track your arm motion (measured by the accelerometer) when estimating results including progress towards your Activity app goals.
For the best results, allow the arm on which you are wearing your watch to swing naturally as you move around and during workouts (where relevant).
If you would prefer to receive Exercise credit for the full duration of workouts, regardless of their estimated intensity levels, track them via the Workout app using "Other" as the activity type. This will credit one minute of Exercise for each full minute of the workout. Active calories will be estimated at a rate equivalent to a brisk walk or based on data recorded by the heart rate sensor, whichever is higher.
To help improve the accuracy of estimations made by the Activity app (and Workout app):
Keep your personal information accurate:
- On your iPhone, in the Watch app, go to: My Watch (tab) > Health > Edit - tap and adjust items, then tap on Done.
Calibrate your watch:
- Calibration teaches your watch how your arm movements relate to your stride lengths at different speeds when you are walking and/or running.
- It does this - during outdoor walks and/or outdoor runs - by comparing data from the accelerometer with GPS / Location Services data.
