Opening method of pedometer:

First of all, in the "Health Data" of the health application, find the "Fitness Data" column and click to enter.

Secondly, you can see the number of steps, frequency+distance and so on. After clicking enter, you can view the detailed data.

Third, I take the number of steps here as an example, and I can see the frequency of my walking now. In addition, it is suggested to check "Show in chart summary". Item so that you can view it directly in the chart summary column later.

To sum up, you can turn on the pedometer and check the steps.
