    Hi

     

    When comparing calorie data between apps, keep in mind that Apple Watch reports active energy / calories, whereas many other fitness apps report total energy (resting + active calories).

     

    To help improve the accuracy of distance (and other) activity-related estimations made by Apple Watch, you can 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 from your iPhone.

     

    For the best results from the Workout app during indoor treadmill activity, it is therefore important to allow your arm to swing naturally as you walk / run.

     

    It may also help to reset your calibration data and start afresh:

    On your iPhone, in the Watch app, go to: My Watch (tab) > Privacy > Motion & Fitness > tap on Reset Calibration Data.

     

    To calibrate your watch, follow the instructions in the support article below, including:

     

    • Record Outdoor Walk and/or Outdoor Run workouts using the Workout app on your watch.
    • Do this for around 20 minutes at each of the speeds at which you normally walk or run.
    • Whilst doing so, take your iPhone with you, with Location Services turned on.
    • Allow your arm to swing naturally during the workout.

     

    Activity estimations also depend on your personal information. To check that this has been entered accurately and to update it over time:

    - On your iPhone, in the Watch app, go to: My Watch > Health > Edit (upper-right).

    Hi Jonathan,

    Thanks for your revert. Would you know why there would be variance in the distance?
