With the release of iOS 14, there are new guidelines for participating in Apple Family Sharing outlined by Apple. At this time, Calm is not participating in Apple Family Sharing, as we are still working to develop the best experience possible for families who share Calm with each other, including discounts for groups.
Because the app itself is added to the Family library of apps once it's downloaded by a family member, it is still considered a 'Family Sharing' app, which is why the App Store details state that. However, the in-app products are not eligible.
If you are interested in sharing Calm with your family, please reach out to our support team here to discuss other pricing options.
