Hi ,

Thank you for your question. Family Sharing is a part of Apple's licensing agreement for the home use of apps purchased through the App Store. The GoTalk NOW app follows Apple's licensing terms for home-use, schools, and businesses.

To share the app between family members, I would recommend this document from Apple that provides clear instructions on setting up Family Sharing.

Once you have the app installed on multiple devices, we can provide support if you have questions about the GoTalk NOW app or sharing individual GoTalk NOW documents between devices.

Please let me know if you have additional questions.

Thanks,
