My watch isn’t tracking all of my steps. How do I fix this?

Hi karlie2477,

We understand that your Apple Watch is producing inaccurate activity measurements. Take a look at the steps and article below for calibrating your Apple Watch to correct the issue.

1. "While wearing your Apple Watch, go to a flat, open outdoor area that offers good GPS reception and clear skies.
2. If you have Apple Watch Series 2 or later, you just need your Apple Watch. If you have Apple Watch Series 1 or earlier, bring your iPhone for GPS. Hold your iPhone in your hand, or wear it on an armband or waistband.
3. Open the Workout app. To start, tap Outdoor Walk or Outdoor Run. To set a goal before starting, tap the ... icon.
4. Walk or run at your normal pace for about 20 minutes.
