In terms of sports, Apple Watch has specially launched two new applications: fitness and exercise. Users can set sports types and targets on Apple Watch, and the watch will record data in real time, so users will be motivated. The data monitored by Apple Watch can also be seen on the iPhone.

Cook said that Apple Watch will change the way we exercise, such as recording the heartbeat, recording the position with the iPhone's GPS, measuring calorie consumption, exercise time and distance. ?

Apple Watch has built-in "activity" and "physical training" software directly. The former is used to count the time of users' activities, sports and standing in a day, and the statistics are divided into three circles: red, blue and green.

The latter can set training objectives, such as time, distance, calories and other units, which will inevitably have a partial impact on many smart bracelets calling for exercise in the market at present? .

According to the information provided by the supplier, Apple Watch has built-in 8GB of storage space. Because Apple Watch can install all kinds of application software, more storage space is indeed a demand. Apple also provides a development module called WatchKit for developers from all sides to develop.
