Bible Explorer by OCC
Read full descriptionHide full description
The whole Bible, with the tools to study it, on your phone. No signal needed. Bible Explorer is built by Ontario Community Church, a congregation of about sixty-five in Ontario, Oregon. Everything in it is public domain, and the Bible and its study tools ship inside the app, so it works on a plane, in a canyon, or in the back row — what a small church can do with a little, given back. READ • Twelve translations: King James, American Standard, World English, Young's Literal, Darby, Webster, Douay-Rheims, Geneva (1599), Revised Version, Tyndale New Testament, JPS Tanakh, and Brenton's Septuagint • The church's own serif type, gold verse numbers, four reading themes (OCC, Parchment, Slate, Midnight), your text size and spacing • Tap any verse for commentary in a split-view pane, cross references, Strong's, and the verse in every translation at once • Tap any reference inside a commentary and it opens right there in a half sheet, with translation chips to compare it on the spot • Type a reference like John 3:16 and jump straight there, or search a phrase across the whole Bible • Focus mode, a verse of the day, top verses, your own reading streak, and picking up right where you left off STUDY • Nine commentaries, all built in: Matthew Henry, Jamieson-Fausset-Brown, Adam Clarke, Keil & Delitzsch, John Wesley, Barnes' Notes, the 1599 Geneva Bible's own marginal notes, John Calvin, and John Gill • Strong's Hebrew and Greek under every word, with that word's occurrences across every translation • Nearly a million cross references and more than 32,000 topics • Six Bible dictionaries: Easton, Smith, Hitchcock, ISBE, Nave's, and Torrey's • More than 3,000 people and 1,300 places, each with a map, its dictionary entries, and every verse that mentions them • Gustave Doré's 1866 Bible engravings, a downloadable illustrations pack linked right to the people, places, and chapters they depict • 718 hymns tied to the verses that inspired them • 24 reading plans, each with a preview before you start SAVE • Bookmarks, highlights, and your own notes and study notes, sorted by reference • Share cards for any verse, in four scenes to match the app's own themes • Everything syncs across your devices through your own iCloud account ALSO • An Apple Watch app: verse of the day, today's plan reading, bookmarks, and a full KJV reader on your wrist • A Messages app: send a verse card in iMessage straight from Verse of the Day, Bookmarks, or a KJV search OFFLINE • No account, no ads, no tracking, no subscription, no AI. Every translation, the nine commentaries, and the six dictionaries are built in. More books and art, and the Greek and Hebrew originals, are free optional downloads • Every translation, every commentary, and every dictionary in Bible Explorer is public domain WHAT MAKES IT DIFFERENT No account.
