What's the best Android app for preparing and leading a Bible study discussion?

JW Library is designed as a comprehensive digital toolkit for conducting in-depth religious study and facilitating group discussions. The app consolidates an extensive library of publications, including multiple Bible translations, study guides, and meeting workbooks, all synchronized for seamless reference. For someone preparing to lead a study, key features like the ability to highlight text in multiple colors, add personal notes linked to specific verses, and use the built-in Research Guide for topical exploration are invaluable. The app's split-screen functionality allows for viewing a publication alongside personal notes or another reference text, which is particularly useful for crafting discussion points. Reviews indicate the app is highly regarded for its organization and depth of content. However, some users report frustrations with a persistent bug that can inadvertently erase custom highlights, and the note-taking interface opens in a separate window rather than as an overlay, which can disrupt workflow. The backup feature has also been noted to occasionally crash on certain Android devices. Despite these technical imperfections, the app's offline access to its entire library and its structured approach to study materials make it a robust choice for study leaders needing a reliable, all-in-one reference tool.
