How do I add my wife's profile to my Apple TV+ account?

To share an Apple TV+ subscription with family members, one should form a Family Sharing group, where several Apple Accounts can share certain services. Each user should have their own Apple Account.

Setting up a Family Sharing group has to be done on an Apple device (iPhone, iPad, iPod touch, Mac).

One user in the group would take on the role of Organizer, and invites the other prospect group members, each by their own Apple ID account. Have them each create an account, if they do not have one yet. This inviting should be done on the organizer’s iPhone, iPad, iPod touch, or Mac. The people that receive this invitation then choose to accept or decline. That’s it, then the Family Sharing group is established, and then the shareable subscription content will be available to all group members. Then each of the members get access through their own account; without the subscription account credentials themselves being shared. The subscriber and the organizer do not have to be the same person.

Family sharing is pretty simple and straight forward. Not understanding something is not the same thing as it being complicated.

If you choose to have everyone use your account, then yes, it will be pretty messy, hence Family sharing, so it's not messy and every user gets their own view and separate watch lists.

I suggest you look into Family Sharing before writing it off entirely.

I never buy an Android device because I find them completely impossible to use. To you they may be very easy. The difference is what you take the time to learn to use and understand.
