I’m happy to announce that Theodia is now available on the App Store and Google Play.
It’s a Bible app built for people who actually want to study Scripture — not just scroll through it.
Why I built it
Most Bible apps lean hard on an internet connection. Lose signal, and suddenly your study tools disappear. Theodia is different. It’s offline-first by design: Bibles, commentaries, lexicons, cross-references, and even hymn lyrics live right on your phone. Read, search, bookmark, and take notes anywhere.
What you get
- 9 bundled translations including KJV, BSB, NET, LEB, WEB, ULT, UST, OHGB, and TRLIT — plus a growing downloadable library
- Parallel reading across up to four translations at once
- Study tools like Strong’s numbers, interlinear Hebrew and Greek, morphology, glosses, and verse-level cross-references
- 2,000+ hymns, fully offline
- Bookmarks, highlights, and notes that stay on your device and can be exported
- 27 interface languages, with Hebrew and Arabic handled right-to-left automatically
- Theophilus, an optional AI study assistant you can connect to any OpenAI-compatible endpoint you choose
- No subscriptions. No ads. No data collection.
Theodia is a one-time purchase that unlocks everything — no in-app purchases, no ads, no donation prompts, and no subscription. Privacy is built in: no account, no analytics, no crash reporting, no advertising ID. Your reading, notes, and bookmarks stay yours.
