Did you know that you’re supposed to calibrate your Apple Watch when you first get it?

This guide will walk you through the process step by step, ensuring that your Apple Watch is properly calibrated in order to accurately collect your health and fitness data.

Why It’s Important to Calibrate Your Apple Watch

The calibration process is needed for your Apple Watch to accurately measure performance while tracking your workouts.

Without proper calibration, your watch may display inaccurate distance, pace, and calorie count information during your walking and running workouts.

By doing this, you’re essentially fine-tuning its algorithms and sensors to better align with your personal movement patterns and stride length.

Preparing for Calibration

Before you begin the calibration process, there are a few things you need to prepare:

How to Calibrate Apple Watch

To calibrate your Apple Watch, you need to first activate it, then start an outdoor walk or run.

Follow these instructions:

1. Enable Motion Calibration & Distance

  1. Open the “Settings” app on your Apple Watch.
  2. Scroll down and tap on “Privacy.
  3. Select “Location Services” and make sure it is toggled on.
  4. Then, open the Watch App on your iPhone.
  5. Scroll down to “Privacy“.
  6. Toggle on “Fitness Tracking“.

2. Start an Outdoor Walk

  1. Open the “Workout” app on your Apple Watch.
  2. Start an outdoor walk or run workout. It must be for a minimum of 20 minutes.

Once you end your workout, your Apple Watch will use this data to calibrate its tracking algorithms.

Note: For those with Apple Watch Series 2 or newer, only your Apple Watch is required. However, if you own an Apple Watch Series 1 or an older version, you need to also carry your iPhone to use its GPS.

Tips for Maintaining Accurate Calibration

To maintain optimal tracking accuracy, it’s important to follow these tips:

  • It could help to complete the calibration in different environments, such as flat and hilly terrains.
  • Perform the calibration process for various walking and running speeds.
  • Update your personal information, like height and weight, in the “Health” app on your iPhone.
  • Regularly calibrate your watch, especially after watchOS or iOS updates.

Troubleshooting Calibration Issues

If you’re experiencing issues with your Apple Watch’s calibration, try the following:

  1. Reset your calibration data in the “Privacy” settings on your Apple Watch.
  2. Ensure that your watch is snugly secured on your wrist during workouts.
  3. Disable power-saving mode in the “Workout” settings to allow continuous heart rate tracking.
  4. Reach out to Apple Support for further assistance if the issue persists.
