Using Wi-Fi networks and GPS satellites, the device can also gather information that is used in determining its specific location at any point and any place. The data from the Apple watch are provided by the two built-in sensors, accelerators and infra ray sensor. One reports the movement of the body. The other reports the expansion or shrinkage of blood vessel. The data collected by the accelerator sensor will then used by the apps to derive one’s workout and activities. The data collected by the infra ray sensor will be used by the app to decide the heart rate. This device enables the user of the watch to track the intensity of jogging and gym activities as well as walking and other exercises being done in the neighborhood. On the other hand, the sensor devices are quite passive. It tracks light exercise session like movements that the user makes during the day. These exercises may have been done within a minute or 12 hours. The activity and workout apps work alongside the Healthkit framework and health app, which have been announced by the company as having been incorporated in its iOS 8 [Guar2015]. Apple develops the HealthKit to enable sharing data between the new health app and between the apps that provide health and fitness. Also, by using the HealthKit any app that provides health and fitness services can share date among each other. Managing the data from different sources and merging the data from all sources based on the user choice is the HealthKit design functionality. Apps who are using the HealthKit are able to access the data from any source and do their own changes or merging’s on them. The user of the main health app can choose which data to share because he is sure that his health information is safe and secure in the Apple health database. The HealthKit also provides storage service that synchronizes the local health data on apple watch with those in iPhone and iCloud. [Appledeveloper].
