Use this B&H Kit to track and record multiple data points about your activity levels, body composition, and general fitness grade. This kit includes a black Fitbit Flex Activity + Sleep Wristband and a black Fitbit Aria Wi-Fi Smart Scale. The Flex records the number of steps you take, distance traveled, calories burned, and more. It also tracks your sleep at night and features a silent vibrating alarm to help you wake peacefully. The Aria measures and records your weight, Body Mass Index (BMI), lean mass, and body fat percentage. The Aria also remembers up to eight individual users, so whenever you step on the scale, it recognizes you and displays your body composition statistics.
Both devices can wirelessly sync your data to a compatible smartphone and computer, which can then be viewed on Fitbit's website and mobile app. The Flex uses the included wireless dongle to connect to your computer and syncs via Bluetooth to your compatible smartphone; the Aria connects to your device wherever there is a Wi-Fi connection.
Fitbit's website and mobile app allow you to see all your activity and fitness data in one place, so you can track your progress over time, analyze your habits, compete with friends in fitness challenges, and more. The website and the app are connected, so when you sync data to one device, it appears on the other as well.
