Theodia

Reference

$0.99 · Designed for iPad. Not verified for macOS.

Theodia is a powerful Bible reader and study companion that works entirely offline. No internet connection, no login, and no subscription required to read, search, and study Scripture. Designed for both phones and tablets, Theodia gives you the same full study experience on a tablet with adaptive layouts, keyboard shortcuts, and split-view multitasking. Theodia is built for pastors, students, translators, and anyone who wants the full text of Scripture — and the tools to study it — in their pocket, with or without a signal. READ THE BIBLE YOUR WAY Nine translations are built in, including KJV, BSB, NET, LEB, WEB, ULT, UST, OHGB, and TRLIT. Download free additional translations, commentaries, books, and devotionals inside the app. Read up to four translations side by side in Parallel Bible view, or compare any verse across every installed translation with one tap. Hebrew texts automatically render right-to-left, and Focus Mode gives you a clean, distraction-free reading experience. STUDY WITH BUILT-IN TOOLS The app includes Matthew Henry's commentary and an AI Book Summary, with more commentaries available as free downloads. Five lexicons include Strong's number lookup, cross-references are available for every verse, and the Word Info / interlinear view shows morphology, gloss, and original-language text. Full-text search works across every installed translation at once, with book-range filtering. HYMN LYRICS INCLUDED A built-in library of over 2,000 hymns, available offline alongside your Bible study — no extra app required. ORGANIZE YOUR STUDY Save bookmarks into folders such as Sermon Prep, Comfort, and Wedding Readings. Highlight verses with color coding, add notes tied to specific verses, and keep free-form study notebooks. Export bookmarks, highlights, and notes to bring into your sermon-prep or note-taking workflow. LANGUAGES Theodia supports 27 interface languages: English, Simplified Chinese, Traditional Chinese, Spanish, Hindi, Arabic, Portuguese, Russian, German, French, Italian, Polish, Ukrainian, Romanian, Korean, Filipino, Vietnamese, Japanese, Indonesian, Dutch, Hebrew, Thai, Turkish, Greek, Czech, Swedish, and Danish. BUY ONCE, USE FULLY - One-time purchase for full access. - Free upgrades for life. - No monthly fees, ever. - No in-app purchases. - Nothing requires unlocking for a fee. - No ads. - No requests for donations. PRIVACY BY DESIGN - No account, no tracking. - No third-party analytics. - All your data lives on your device. - No data sold or shared. - Your notes and bookmarks stay private. - No AI processing unless you choose it. OPTIONAL AI ASSISTANT: THEOPHILUS Theophilus can look up verses, summarize chapters, pull cross-references, search the lexicon, create bookmarks, and write study notes — all by asking in plain language. Theophilus is entirely optional: Theodia works fully with the AI turned off. When enabled, you choose the model and endpoint, whether a self-hosted server or an API service you provide. Your API key is stored securely on your device and is never logged.
