Did you get a new Apple Watch for the holidays

Activity, shown in Figure 2.22, is designed for use on an ongoing basis, throughout your day. The app takes advantage of the watch’s built-in sensors and continuously monitors your level of movement, exercise, and periods of inactivity (as long as you’re wearing the watch).

As you’ll discover, this information displays in several ways, and syncs automatically with the Activity and Health apps running on your iPhone. The Activity app also shares data with other health and fitness apps, as needed.


Use the Workout App

You use the Workout app, shown in Figure 2.24, for whenever you engage in any type of cardio fitness workout session, such as jogging, running, bike riding, or using an elliptical machine (or treadmill). The Workout app collects and displays real-time stats, such as time, distance, calories, pace, and speed.

Like in the Activity app, the data the watch collects and displays automatically syncs with the iPhone, and a growing selection of other health- and fitness-oriented apps, including the Health app that comes preinstalled with iOS 8.2 on the iPhone, can use this data.

The Health app on the iPhone collects real-time health and fitness-related data from the iPhone, Apple Watch, and other compatible equipment (such as a Bluetooth scale, for example), as well as data you manually input, and then monitors, analyzes, stores, and potentially shares that information from the one, centralized Health app.

Just as Notification Center monitors apps and keeps track of all alerts, alarms, and notifications, and then displays this information in one centralized place, the Health app serves a similar purpose, but deals exclusively with health, fitness, nutrition/diet, and sleep-related data and information.
