How to calibrate the Apple Watch for more accurate fitness tracking

apple-watch-fitness-grab

The Apple Watch is useful as an activity tracker, logging both your daily routine and your workout sessions. To improve the accuracy of your fitness tracking, you should calibrate the Watch, so it can accurately measure your calorie, distance and Move estimations.

The calibration process requires you to use your iPhone and Watch simultaneously as you track a workout session of 20 minutes or more. For the most accurate measurements, you should perform this calibration process both when running and walking since you use different stride lengths for these two activities. Use the following directions to calibrate your Watch:

  1. Bring your iPhone and your Apple Watch to the workout session.
  2. Find a flat, open area outside that offers good GPS reception
  3. Turn on Location Services on your iPhone by opening the Settings app and selecting Privacy > Location Services.location-services
  4. Enable Motion Calibration & Distance on your iPhone by opening Settings > Privacy > Location Services > System Services. Select the Motion Calibration & Distance toggle to turn it on. motion-calibrate [1]
  5. Wear your Watch on your wrist and attach your iPhone to your body using an armband or waistband. You also can hold your phone in your hand.
  6. Open the Workout app on your Apple Watch, and choose Outdoor Walk or Outdoor Run.
  7. Set your goal or select Open for a goal-free session.
  8. Tap Start to begin your workout.
  9. Walk or run for at least 20 minutes.
  10. If you run or walk at different paces, then repeat this process for each of those different speeds.

When you are finished, the Watch will store this calibration data locally and use it to calculate future Workout sessions. Because this calibration data is stored on the Watch and not backed up to your iPhone,  it will be deleted when you unpair your Apple Watch from your iPhone.

This calibration process is not necessary for you to use the Workout or Activity apps; you can use those apps just fine without calibration. This process is recommended if you want the most accurate calorie, distance, Move, and Exercise estimations, especially if you are exercising indoors without the aid of GPS tracking. It’s also useful if you plan to use the Watch away from the iPhone for activity tracking.
