If you want a Bible study app that goes deep — with Strong's concordance, split-screen commentary, and cross-references — without paying a dime or seeing a single ad, AndBible is the tool serious students of Scripture have been looking for.^1
Built by Bible readers, for Bible readers, AndBible is a completely free, open-source Android app with access to over 1,500 documents in more than 700 languages — including Bible translations like KJV, NASB, and NET, plus trusted commentaries from Matthew Henry and John Gill.^2 Its standout features include split text views for comparing translations side-by-side, workspaces that save your study setup, Greek and Hebrew word analysis via Strong's integration, advanced text-to-speech with bookmarks, reading plans with progress tracking, and Study Pads for jotting notes during sermons.^1 It also supports MyBible, MySword, and EPUB files, letting you bring your own library along.^2
Originally developed by Martin Denham starting in 2010, the project is now led by Tuomas Airaksinen under Sykerö Software (Tuomas Airaksinen Software Oy) and sustained entirely by an open-source community and voluntary sponsorships — no corporation, no subscription, no strings attached.^3 Its most recent major release shipped an optional AI-powered study assistant with multi-provider support (Gemini, Claude, OpenRouter), a reading and memorization progress tracker with calendar heatmaps, editable syncable "My Documents," and multi-translation search across Bibles.^4 An iOS version is also in development by contributor Jared Murrell, with an initial release planned for the App Store.^5
