Hi Brett, only one Striiv device can be paired to a Striiv account. You can try creating a separate Striiv account to pair the second device to the same phone, but the device connected to the account you're not actively logged into may not provide all its advertised features. Phone call/text/app notifications for example require an active connection with the device, and logging out of an account usually disconnects the device. Hope this helps!
