A:AnswerYes. The scale can tell the difference between multiple users. You do not have to be wearing your Fitbit when using the scale. It knows who you are by comparing the current readings against the last readings of known users. It may have problems if two users have very similar weight and body fat measurements.
A:AnswerGot this from the website, not sure if it really answers your question, but I believe that it has to do with metrics you input into the fitbit app. Anyway, here is what I got from their site:
Several different methods are available to determine body fat percentage and none are 100% accurate. The Aria measures your body fat percentage using body impedance. Because body fat measurements can be subjective, the Aria's body fat reading may not match other scales or manual methods such as calipers.
To get a sense of what body fat percentage is healthy for you, you may want to review the standard body fat ranges for your age and gender. The following website provides this information: http://www.acefitness.org/acefit/tools-and-calculators/
