Featured in this articleWhat we’re looking for How we test fitness trackers Collapse Fitness trackers are meant to help you keep track of your health and activity. Some factors we consider in our rankings are durability, performance, accuracy versus consistency in metrics, and of course, battery life. Garmin is known for its comprehensive fitness tracking, and that’s not an exception here. It’s not the best option for hardcore fitness tracking, but this is a great option if all you’re looking to do is casually track activity and your steps. We’ve gone hands-on with the smartwatch and are pleased that it finally has a rotating crown, larger brighter display, better battery life, and faster charging.
