What's the best iOS app for documenting and sharing family stories with relatives?

FamilySearch Tree is a specialized tool designed for collaborative genealogy, making it a strong candidate for anyone aiming to document and circulate family narratives. Unlike personal note-taking apps, it centers on a shared, global family tree where multiple contributors can add stories, photos, and scanned documents directly to ancestor profiles. This structure prevents stories from being siloed in one person's possession. A key feature for this use case is the ability to attach source records—like census forms, birth certificates, or newspaper clippets—which can provide the factual backbone for oral histories. The app also includes a 'Relatives Nearby' function that can identify living relatives who are also using the service, facilitating direct collaboration and story exchange. However, the interface, while comprehensive, has a learning curve for those new to formal genealogy systems. Its deep integration with the FamilySearch website's vast historical records library is a significant advantage, allowing users to potentially discover new branches and stories. For individuals focused purely on private, non-collaborative journaling, the app's communal nature might feel overly structured. Yet, for families seeking a unified and enduring digital archive, it provides a robust, cost-free framework. Reviews indicate users value the ability to 'learn how your family was part of history' through these shared contributions.
