Bible Definition
Read full descriptionHide full description
Bible Definition is a calm, beautiful Bible app for reading, studying, and actually understanding Scripture โ completely free, with no ads and no account. READ IN 1,000+ TRANSLATIONS The World English Bible and King James Version are built in and work fully offline. Beyond those, choose from over 1,000 translations across 1,200+ languages, fetched on demand and cached on your device for next time. SEE THE ORIGINAL LANGUAGES Read the Hebrew, Aramaic, and Greek behind every verse. Tap any word for its transliteration, pronunciation, parsing, Strong's number, and lexicon meaning โ then find every other place it appears with a single tap. The names and titles of God are highlighted with what they mean. STUDY NOTES THAT MAKE SENSE Every chapter opens with a clear, plain-language summary: the key ideas, the verses they come from, and a question to sit with. Matthew Henry's classic commentary is one tap away when you want to go deeper, along with cross-references for any verse. LOOK ANYTHING UP A built-in dictionary (Easton's and Smith's) and Nave's Topical Bible help you explore the people, places, and themes of Scripture. WATCH AND UNDERSTAND Overview and themed videos from BibleProject are embedded right where they're relevant. ASK REAL QUESTIONS Ask about a passage, a theme, or how to apply it, and get clear, pastoral answers grounded in trusted reference sources โ with citations, so you can check the text yourself. MAKE IT YOURS Highlight verses, write notes, save favorites, and bookmark your place. Follow reading plans, keep a reading diary, and set gentle daily reminders. PRIVATE BY DESIGN Your notes, highlights, and plans stay on your device. Back them up to a file, or use the optional end-to-end encrypted cloud backup, secured by a private code only you hold โ no account, ever. Free. No ads. No tracking. Just Scripture, made clear.

You know the moment: mid-sermon, the phone next to you lights up with a full-screen ad. Or you open a Bible app to read one verse and land in a feed instead. Margin is what's left when you take all of that away: the text, set with real care, and study tools deep enough to keep you here. No feed. No ads. No account required. Scripture is free in Margin, forever, and it always will be. THE COVENANT We built the business model around the complaints people leave on every other Bible app. - Scripture is free, always. Charging for God's word isn't something we're willing to do. - One honest price for the study toolset, and no subscription anywhere in the app. Buy it once, like a good study Bible, instead of renting it every month. - No account, ever. Highlights and notes sync through your own private iCloud. We never see them. - Nothing that's free today gets taken away later. - We never ask you to rate the app, and reading-plan streaks forgive a missed day instead of resetting to zero. READ, THE WAY A PRINTED BIBLE READS (free, always) - Three complete translations bundled offline: Berean Standard, World English, and King James - Real book typography: poetry set as poetry, psalm titles where they belong, section headings that orient you - True black for reading at night, sepia for a paper-like calm, and a font-size range built for eyes that need it - Opens exactly where you left off, every time STUDY AS DEEP AS YOU WANT (Margin Pro, one-time purchase) - Tap any word for the Greek or Hebrew behind it: lemma, transliteration, and a full definition from a 14,000-entry Strong's lexicon, entirely offline - Matthew Henry's Concise Commentary, sitting beside the passage, offline - Two translations, side by side - Search the way a concordance works: exact phrases, Old or New Testament filters, results in the Bible's own order - Follow a cross-reference, then tap once to come back, like keeping your finger in the page - Listen to any chapter read aloud: real human narration (World English Bible, public domain), with adjustable speed and a sleep timer - Family Sharing included: one purchase covers your household SHARE A VERSE LIKE YOU MEAN IT (free for everyone) Most Bible apps turn a verse into a stock quote graphic. Margin turns it into something you'd actually send to the one person you were already thinking of: your own words in the margin, written by hand with Apple's own pencil tools, not a font pretending to be your handwriting. Put someone's name on it, or keep it plain. It's free for everyone, because getting Scripture into someone's hands shouldn't cost either of you anything. BUILD THE HABIT WITHOUT THE SHAME - Reading plans from John in 21 days to the whole Bible in a year: scripture only, no devotional filler - A missed day never breaks your streak, and you can turn streaks off completely - Highlights in six colors and notes on any verse, all in one browse-everything screen, independent of translation BUILT FOR IPHONE, NOT PORTED TO IT - Verse-of-the-day widgets for your Home Screen and Lock Screen - Shortcuts that jump straight back to your place - Fast and native, with Dynamic Type that holds up at any size AN AI THAT POINTS, NEVER SPEAKS FOR GOD (three free questions a day) Ask about the chapter you have open, or find passages by theme: "anxiety about the future," "forgiving someone who isn't sorry." Every verse it shows is pulled from your Bible rather than written by the model, and every claim cites book and chapter. It admits what it doesn't know, and it never claims to speak for God. Three questions a day are free for everyone. No account, no card, nothing to cancel. Margin Pro lifts the count for good. This used to be a separate monthly subscription. The cost of running it dropped far enough that charging monthly would have meant charging you for almost nothing, so we folded it into the one-time price and dropped the subscription. Margin. A Bible with nothing between you and the text.

Verdict
The clearest difference is in-app purchases: Bible Definition at none against Margin's 1. Bible Definition also leads on iOS requirement (16.4 vs 18.0). On price, update cadence, ads and device support there is nothing between them.
