Charge 4 Sharing

[Zabbo_fit]

Can a single Charge 4 device be used by two people?  Is there a way to keep there Fitbit data separate?

Does the Charge 4's algorithm learn as you wear the device longer. In short, does it measurements and predictions improve the more time you wear it, and customizes to the host?  Or would there be no difference in its data reporting metrics for two different users?

Hi @Zabbo_fit  you can, but it will require some real effort on your part. You each need your own email address and account. When User 1 has the Charge 4, they are set up with their account. When it's time for User 2 to use it, User 1 has to log out and User 2 has to set it up as their device on their account. Be sure to sync before letting the other user have it. See, it's a bit of work to do and both of you will need compatible phones, but you could also share those too. That's the only way to do it.

@Zabbo_fit  the Fitbit would need time to get used to how you move, how active, etc. It uses your account information (age, gender, height, weight) as well as your heart rate, etc. So two different people would naturally have completely unique stats. Not sure what you're planning on doing with two people using the one Fitbit, but most of the time it takes two weeks to get sleep and oxygen saturation data. Care to share more what it is you want to do? The more information, the better to assist you.
