It's hard to stand out in the fitness tracker world when you can easily cover the fundamentals at a very low price. Garmin, however, is trying its level best. It just launched the Vivofit 4, which combines an always-on color display with its predecessor's claimed year-long battery life. You can now check your activity goals or the time without having to either wake up the screen, kill your battery or settle for a drab monochrome display. Logically, the band includes Garmin mainstays like Move IQ automatic activity detection and the Connect online community to get you motivated.
