Apple App Store (iPad, iPhone, iPod, Mac)
Yes, the Starfall App now supports Apple's Family Sharing option. Please refer to Apple Support: Family Sharing for information about setting up this feature.
Google Play (Chromebook and Android)
The Google Play Family Library feature does not support sharing subscriptions. Unlike many in-app purchases, Google also limits the ability to purchase subscriptions for other accounts using a family payment method. You will need to use a separate payment method for those accounts. Please visit the links below for more information.
