With the release of iOS 14, there are new guidelines for participating in Apple Family Sharing outlined by Apple. 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, such as subscriptions, are not eligible.
Although Calm is not participating in Apple Family Sharing, we are excited to offer customers the option to purchase a Calm Premium Family Plan. A Calm Premium Family Plan comes with 6 separate accounts that you can share with your family. Learn more here.
