Activity trackers and multi-fitness units, watch out. The Fitbit Blaze is all about training, 24-7 health, and 360-degree convenience in one, simple-to-use watch. Blaze is paying attention each time you take the stairs, the longer way back to your office, and those lunchtime strolls you’ve been trying to get better about squeezing in, capturing your heart rate right at your wrist as you move along. If any daily activity happens to transition to a run or more aerobic-style activity, Fitbit is happy to oblige, automatically transitioning into fitness mode and using its GPS tracking to give you real time stats as you run, ride, or sweat away during a cardio gym class. Plus, if you’re always streaming & listening to music from your phone, you’ll love the music control feature that let’s you quickly turn it UP without messing with your phone.
