What's the best iOS app for tagging and organizing Bible study notes with audio support?

JW Library is an app specifically designed to support in-depth Bible study through comprehensive organizational features. Its tagging system allows users to categorize verses, articles, and personal notes with custom labels, facilitating quick retrieval and structured review. For instance, during personal study sessions, users can tag key themes like 'faith' or 'prophecy' across different publications, creating a personalized reference library. The app also includes audio features with varied voice actors reading scriptures, which helps in auditory learning and retention. Additionally, integrated study publications and marginal references provide context without switching between sources. However, some users report that the inability to delete or merge tags can lead to clutter over time, especially if similar tags are created accidentally. Despite this limitation, the app's meeting preparation layout consolidates all necessary materials, streamlining group study or worship sessions. Overall, JW Library balances powerful organization with multimedia support, though future updates addressing tag management could further improve user experience.
