Read 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.
