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

STUDY TOOLS THAT GO DEEP

STUDY PANELS
Keep what you're studying in view. Study panels stick to the bottom of your screen, or to the side in landscape and on tablets, 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 Strong's number and find every verse it appears in, with matches highlighted. Scope your search by book to focus in. Fast, offline, and built for real Bible study.

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 page.

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. Whether you're a note-taker, a language learner, or a serious studier, Lux adapts to your study habits.

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

READ WITH A PLAN
Choose from Bible-in-a-year plans, including chronological and straight-through readings, or focus on the Gospels & Epistles, Prophets & Chronicles, and more. Filter plans, work through more than one at a time, track each day's progress, and revisit previous readings anytime. Every daily reading opens into the study tools you already use.
