Before you write a negative comment, please consider reading the following tutorial on how to enable Connect IQ datafields on your watch:
https://support.garmin.com/en-US/?faq=gyywAozBuAAGlvfzvR9VZ8

This datafield shows the number of steps taken during an activity. It only records steps when the timer is running. At the end of the session the step data are written into the FIT file for the entire session (total number of steps) and also for the individual laps (number of steps per each lap) so that you can check it in the activity summary on the Garmin Connect website or in the Garmin Connect application. 

For some devices (e.g., Fenix 3 and Fenix 3 HR) the steps data may not appear on the Garmin Connect website and in the application. This is a known bug of the Garmin Connect ecosystem, and hopefully it will be fixed soon. 

If you are interested in the implementation details, check out the project on GitHub.
