Sometimes you might want to pass your Flow around—for example: A family wants to track their kid's air pollution exposure on the way to school. Each person who does the school run has their own phone, so they want to connect the family Flow to their device when it's their turn.
If you want to share your Flow with a friend or family member, you'll have to also share a Flow account. Each Flow is associated with an email address and a user ID, not a specific device. As long as each person is signed in to the Flow app on their device with the correct Flow account, the Flow associated will connect.
Sharing your Flow: Step by Step
Step 1: Create a shared account
This is just like creating a regular account but you might want to use an email and password that you are comfortable sharing with the other person who will use Flow
Step 2: Sign in to the Flow App on the Devices Flow will be used with
Sign in to the Flow App installed on the devices you will be using with username and password for the shared account you just created
Step 3: Connect Flow to the device you wish to use
Launch the Flow App on the device you wish to use Flow with and connect your Flow. NOTE: Flow can only be connected to one device at a time so make sure your other phone's bluetooth is off, or the phone is out of range when you are trying to connect.
