What makes digital story time feel genuinely shared?

I’m building Storio, a small web app for sharing story time with friends and family. The current version includes a library of classic stories and simple Create and Read experiences.

I’m trying to understand a bigger question: what makes a digital story experience feel genuinely shared, rather than just another screen?

For parents, grandparents, families, and makers here:

• Do you prefer guided classics, original stories, or a mix?
• What would make you invite someone else into a story session?
• Which parts of reading together should stay deliberately simple?

If you’d like to see the current experiment: https://storio.web.app/

I’m not looking for upvotes—specific feedback on the experience, audience, or what feels missing would be most useful. Happy to answer questions and participate in the discussion.
