Lux Bible is a Bible reading and study app built on a simple conviction: Scripture deserves better software. It pairs a calm, distraction-free reader with serious study tools, and it works offline, with no account required.^1
You can read multiple translations offline, including the BSB, CSB, KJV, ASV, and WEB, with more translations available online and in other languages.^2 Audio, Verse of the Day, and reading plans you can build, import, and share sit alongside the reader.^2 Highlighting works at the level of a verse, a word, or a phrase, and notes are organized into notebooks you can filter or hide.^2 For deeper study, tapping a word shows its Greek or Hebrew root, Strong's number, and morphology, and a full interlinear, cross-references, and a Strong's lexicon are built in.^2 Linked Resources gathers what connects to the passage you are reading: Tyndale Study Notes, commentary from Matthew Henry, John Calvin, and Jamieson-Fausset-Brown, a Bible dictionary, Bible maps, BibleProject videos, and historic creeds, confessions, and catechisms with their Scripture proofs.^2
Lux is built by JLogical LLC. Its founder, Jake Boychenko, is a senior Flutter engineer who builds apps through JLogical, and he writes about Lux in the first person on the site, explaining that he built it so the study tools he uses regularly would live where he was already reading.^4 His study guide on the SOAP method walks through reading Romans 12 in context, checking a commentary and cross-references, and ending in application and prayer.^5
Lux is free, and the listings state that commitment plainly: no ads, no subscriptions, no in-app purchases, and no accounts.^2 Your notes, highlights, and reading history stay on your device, and the privacy policy states that Lux sends no user-created content to its analytics or crash-reporting services and does not use analytics for advertising or cross-app tracking.^6
