|Apple has officially unveiled the Apple Watch. Available in two sizes and three models(Watch, Watch sport and Watch Edition) - original, with a custom stainless steel alloy case; Sport, with an anodized aluminum alloy case; and Edition, with an 18K gold case in yellow or rose and Sapphire crystal. Powered by a custom S1 processor and the sapphire covered touchscreen. Apple itself has developed two different fitness apps for the watch, too. The “Activity” app is meant to track your movement throughout the day. The “Workout” app, on the other hand, focuses on specific sports. Apple also built a cool way to see your photos. You start out zoomed out, with all of your photos showing as minuscule thumbnails. Then you use the crown to zoom in. The watch uses the same gesture to zoom in and out of Apple Maps, too.
