The Galaxy Watch is on a mission to cheer you up. Samsung have prioritised wellness management on its latest wrist enhancer. There's a tracker that detects high levels of stress, offering corresponding exercises when you're on the brink of blowing a fuse. A sleep tracker keeps tabs on your snoozing. There's 21 indoor exercises and 39 workouts on board. You can log nutritional information and manage calorie intake; and use the watch to control apps and products within the Galaxy ecosystem. For example, turn off the lights and adjust the temperature at home, all while gorging on Spotify through the watch.
