Can a Charge 5 and Inspire 3 use one phone?

[Counting]

I have a Charge 5 I track on my iPhone app. My son doesn’t have a phone. If I buy the Inspire 3 Fitbit for him, can I track it also on my phone in the same app? How would this work?

Correction - it’s an Inspire 2 not 3.

Hello @Counting and welcome to the Community.  You can download only one copy of the Fitbit app on an iPhone.  Your son needs to set up his own account with his own email/password.  When two users share a phone, one person must log out so the other can log in to sync and view data.

You don’t mention your son’s age.  A child must be 13 or older (even older in some countries) to have their own account and use a device like the Inspire 2.  Younger users must use the Ace series, specifically designed for younger users.
