Apple updated its Activity app with new features such as Activity Trends, which compares nine key metrics over the last 90 to 365 days, including how much users walked during a workout and how many flights of stairs they climbed.

Dr. Sumbul Desai, Apple’s VP of Health, introduced two new apps for watchOS, including a Noise app that notifies users if the noise around them reaches dangerous levels that could damage their hearing, as well a “Cycle Tracking” app for tracking menstrual cycles.
