An offline scripture study room that never leaves your iPhone. Here's how to get help with it.

direct · no ticket queueEmail us about anything — a bug, a question about translations, read-aloud, the AI chat, or a feature request. Because Silo Bible runs entirely on your iPhone and we collect nothing, please include your iOS version and what you were doing when the issue appeared; that's usually all we need.

offline · study · privacyYes — that's the point. Download the translations you want from the in-app catalog once, and everything works with no network at all: reading, Strong's Concordance, highlights, notes, bookmarks, reading history, and read-aloud with the on-device voices. The only time the app touches the network is when you choose to download a translation or voice pack.
The catalog offers open-licensed and public-domain editions — including the World English Bible, the King James Version, and the American Standard Version — plus editions in over 1,000 languages via eBible.org. Downloads are anonymous; no account is needed.
Tap any word in the text to open its Strong's Concordance entry: the original Hebrew or Greek word, its transliteration, and its definition. It works offline, right in the passage, so you can study the original language without leaving the chapter.
Silo Bible reads scripture aloud with on-device open-source voices (or the system voice, if you prefer). It works fully offline, with lock-screen playback controls and a sleep timer for listening at night.
The AI chat runs via Apple Intelligence on iOS 26+ devices that support it. Questions are answered from the text of the Bible itself, with verse citations, and everything runs entirely on the device — nothing you ask ever leaves your iPhone.
On your iPhone, and nowhere else. Highlights, margin notes (including the handwritten style), bookmarks, and reading history all stay on the device. There is no account, no sync server, and no analytics — we never see your study.
No. Silo Bible is a one-time $9.99 purchase. No subscription, no account, no in-app data collection — you buy it once and it's yours.
