Fitness App not tracking stairs.

Hello Isha10fla,

From what you've shared it sounds like your Activity is not being recorded correctly. The best steps you can take to correct or improve this behavior can be found here: Calibrate your Apple Watch for improved Workout and Activity accuracy - Apple Support

Check your settings

To make sure that your Apple Watch can get the information it needs, check these settings on your iPhone:

1. On your iPhone, open the Settings app.

2. Tap Privacy & Security > Location Services. 

3. Make sure that Location Services is turned on.

4. Scroll down, then tap System Services. 

5. Make sure that Motion Calibration & Distance is turned on.

6. Continue with the steps below.

Once you've taken these steps continue with "Calibrate your Apple Watch".

Take care!

My bad my first response has rendered me important due to lack of attention to the fact that instructions for calibration for the Apple Watch being not here is in fact…here
