Your activity level is continuously displayed on your Withings Go. The graduations on the outer edge of the screen indicate your progression, based on your daily step goal.
Once you've reached your goal, a star is displayed at the center of the screen and the outside graduations are reset. You can now try to complete another round if you're up for it!
If you reach your goal several times on the same day, an extra graduation is displayed around the star. Challenge yourself to get as many of those as you can!
You can find more details about your activity and check your full history directly from the Withings Health Mate® app.
