Do you know what’s stupid? Pay multiple times for a subscription service so everyone in your family can enjoy it. The good news is, those days are coming to an end thanks to Apple̵
Developers must enable the feature as it is disabled by default. Some may choose not to make their subscriptions shareable depending on how the app works. For example, developers of apps that use IAP for weather data can choose not to enable the feature, as dev-side weather services can be expensive. For example, a shared subscription or in-app purchase can push the app to a place where it is no longer profitable. In addition, consumables cannot be shared for obvious reasons.
Apple’s developer portal says:
Family Sharing provides a streamlined, convenient user experience and can help you attract subscribers, encourage paid subscriptions, increase user engagement, and improve retention. Sales and Trends reports will be updated shortly to give you insight into family plan performance.
One of the first apps to enable this feature is the writing app Ulysses. I got an App Store notification this morning to let me know that my monthly subscription can now be shared with the rest of my family.
So far, this is the only app we’ve seen that has this feature enabled, but I’m sure more will come as time goes on. Developers will have to assess whether they can afford to make it happen.
