Lux: Bible

Lux Bible: modern Bible study, offline-first and permanently free. Full interlinear Greek and Hebrew, original language texts, Strong's numbers, cross-references, commentary, and guided Bible reading plans. Serious study tools in an app that's actually a pleasure to use.

ORIGINAL LANGUAGES, MADE APPROACHABLE Tap any word to see its Greek or Hebrew root, Strong's number, and morphology. Lux brings real interlinear study to your phone.

STUDY TOOLS THAT GO DEEP

• Interlinear with morphology and inflection data
• Strong's Lexicon and Easton's Bible Dictionary
• Cross-references powered by OpenBible
• Commentary from Matthew Henry, John Calvin, and Jamieson-Fausset-Brown
• Compare translations side by side

STUDY PANELS Keep what you're studying in view. Study panels stick to the bottom of your screen on iPhone, or to the side in landscape and on iPad, and hold parallel Bibles, commentary, cross-references, your annotation notes, and more. Open several and swipe between them so everything you need stays on screen as you read.

SEARCH THAT UNDERSTANDS SCRIPTURE Search any word or any Strong's number and find every verse it appears in, with matches highlighted. Scope your search by book to focus in.

HIGHLIGHT THE WAY YOU THINK Highlight by color, underline, or squiggly line, and label each style so you remember what it means. Group your annotations into notebooks, filter them by notebook or highlight style, and hide a notebook to clear it from the Bible.

BUILT AROUND HOW YOU READ Tell Lux what kind of reader you are and it configures itself to match. Customize your toolbars, choose your shortcuts, and move through scripture with fast keyboard-driven navigation and swipe-to-undo.

TRANSLATIONS Berean Standard Bible (BSB), American Standard Version (ASV), King James Version (KJV), and the Dutch Statenvertaling (SVV), all available offline. New International Version (NIV) and New American Standard Bible 1995 (NASB) are available online.

READ THE ORIGINAL TEXTS Go straight to the source with original language Bibles, all offline: the Greek Septuagint (LXX), Textus Receptus (TR), Byzantine Textform (BYZ), and Statistical Restoration (SR) Greek New Testament, plus the Open Scriptures Hebrew Bible (OSHB).
