In addition to tracking your activity, the Fitbit Flex 2 also has an auto sleep tracking feature. The device will monitor your how long you sleep each night, as well as the quality of your sleep. This is a great feature to have in a tracker, as it’s completely effortless to track your sleep habits over time. There’s also an option to set a “sleep goal” – the number of hours of sleep that you’re reaching for each night. If you’d like to set an alarm on your watch for the next morning, it will wake you up with a vibration rather than a loud noise.

The SmartTrack feature of the Fitbit Flex 2 is one of the most advanced features of any fitness tracker on the market today. Fitbit designed this watch to be waterproof, so it’s perfect for swimmers or just anyone who might occasionally take a dip in the pool. The Reminders to Move feature sends you a reminder to get up and get active if you don’t take at least 250 steps within the first 50 minutes of each hour. The alert comes in the form of a magenta light, two white lights, and a vibration. The minimum goal is set at 250 steps per hour.
