The Fitbit Aria 2 White looks like a normal digital scale, but isn't. The special thing about this personal scale is that you can connect it to your Fitbit activity tracker and synchronize it with the Fitbit apps. This ensures your fat percentage, BMI, and weight are displayed clearly in charts and you'll always have this information available. The scale has a memory that accommodates up to 8 people. You don't have to worry about other users being able to see your weight. By using your account this information stays private. You can also set yourself goals in the app and when you've reached a goal, you can share this with your friends.Note: using a scale with body analysis may lead to health risks for certain people such as pregnant women, children, or people that use medical electronic devices. Before use, check the manual for the safety measures and to see whether the scale is suitable for you.
