I'm not an early adopter; I usually wait for the second generation product. I want the company to work the kinks out. Hence, my circumstance with my Series 2 Apple Watch, my first Apple Watch. I could tell you all of the wonderful things of which this little gadget is capable (and perhaps I will another time), but for now I want to focus on one singularly distinctive feature.
Activity encapsulates your day's activities in wonderful little concentric rings. At the beginning of the day one starts with a blank slate. The rings grow in length throughout the day based on preset goals established by the user.
One is literally closing the loops while working toward achieving the day's goals. As a former user of a different exercise tracking band I can say the visual cues are a superior incentive. They watch also reminds one to stand if one has been too sedentary for too long.
The iPhone tracks and displays statistics in daily, weekly, and monthly formats.
The myriad of uses make the watch beneficial, but incentivized fitness along with statistical analysis and progress make the watch a useful fitness tool.
