Why would you need to know the Fitbit model you have?
Different Fitbit models, including Flex, One, Zip, Charge, and Charge HR, come with different features and compatibilities.
Knowing the Fitbit type you have lets you know what it can and what it cannot do. It also lets you know Fitbit’s compatibilities. (Once you know the model you have, head over to https://www.fitbit.com/ to check out the Fitbit’s features and compatibilities).
You will also need to know the Fitbit type you have so that you can set it up with the FitBit App. Once you download the Fitbit app on your phone, you will need to choose the Fitbit Type you have for setting up.
