Quick read
Blue Letter Bible in plain English
Blue Letter Bible gives users many Bible study tools for free. Its apps work on iPhone, iPad, Android, web, and some Macs. Apple lists more than thirty Bible texts in the phone app. Word links tie Bible terms to Strong's numbers and source words. Word books, study notes, and side-by-side texts aid close study. Search, notes, saved verses, and marks work on phone apps. Some Bible texts can be saved for use with no web.
Sound is on offer, but full offline sound is not proved. The pages do not promise full sync for each saved note. No AI chat or plain-word search tool appears in the pages. The free plan puts word tools in reach of more users. It has less device reach than the top apps here. Blue Letter Bible ranks seventh in the full list. It is our top free pick for Greek and Hebrew lookup.
Original synthesis
Who should choose Blue Letter Bible?
Blue Letter Bible is our free-study winner. It cannot match Logos for library depth or Olive Tree for a polished paid-resource workflow, but it puts serious language and commentary tools within reach at no charge. Readers who do not need chat AI or broad device sync may reasonably prefer it to every app above it.
What the sources show
- Interlinear views, Strong's numbers, lexicons, dictionaries, and commentaries are free.
- More than 30 translations, advanced search, parallel reading, and text or audio commentaries support close study.
- Notes, highlighting, underlining, and cloud backup cover personal annotation.
- The website gives desktop readers access without buying a separate edition.
Limits to know first
- The current sources do not prove full annotation sync with the same breadth as Logos, Olive Tree, or YouVersion.
- There is no documented AI assistant or natural-language semantic search.
- The official listings do not promise downloadable audio.
- Platform coverage stops short of native Windows, Linux, watches, television, and car dashboards.
Plain definitions
Three terms in this review
Interlinear Bible means a view that aligns translated words with the underlying Hebrew, Aramaic, or Greek text.
Strong's number means an index number that links a biblical word to a dictionary entry and other occurrences. It is a lookup system, not a translation.
Cloud backup means a remote copy of notes and settings that can help restore data. Backup does not always mean instant two-way sync on every device.
For example, a reader can tap a word in an English verse, open its concordance and interlinear record, check a lexicon, compare translations, then save a note. That workflow is fully documented and free. It should not be confused with reading advanced grammar automatically or receiving a generated interpretation.

Score note. Initial 2026 baseline. Study and value score highly. Sync, offline audio, and platform breadth receive partial credit because the official records are narrower or less explicit. See how we score each app.
Reading and translations
What the reader and catalog cover
The app combines more than 30 translations with search, parallel views, themes, font controls, autoscroll, notes, and highlighting. That is a smaller language catalogue than Bible Expert or YouVersion, but the selection connects directly to a much deeper free study layer. Some text can work offline; licence terms vary by translation.

Study, search, and AI
Study tools and proof
A tap on a verse opens interlinear data, Strong's entries, lexicons, dictionaries, and commentaries. Text and audio teaching resources are tied to Scripture rather than scattered across a general content feed. This is old-fashioned Bible software in the best sense. It exposes source material and lets the reader do the interpretive work.

Audio and offline use
What works with no internet
Audio Bibles and audio commentaries are part of the app. Official pages do not make a universal download promise, so we treat audio as primarily connected. Travellers should test the exact translation and media item before relying on it away from a network.

Documented limitations
- Some translations have licence-based offline limits.
- Audio availability differs by version.
- Cloud backup is documented more clearly than live multi-device continuity.
- No generative or semantic AI tool appears in official product material.
Devices and continuity
Device support and sync
iPhone, iPad, Android, and a capable website cover the main screens. Cloud backup protects notes and personalization. The documentation does not establish the same real-time, all-device annotation model claimed by the highest-ranked sync systems, and there are no documented watch, television, car, Windows, or Linux apps.
Cost and privacy
Cost and data use
There is no paywall around the headline study tools. That is exceptional value. Blue Letter Bible publishes privacy terms and accepts donations. Cloud backup adds convenience but also means personal study notes may leave the device, a point worth checking before storing pastoral or private information.
The official mobile listings present the app as free. Blue Letter Bible operates as a ministry and accepts donations.
Blue Letter Bible publishes a privacy policy and the stores provide platform privacy labels. Account or cloud-backup functions necessarily move saved material beyond one device. Readers who write sensitive notes should review those terms before enabling backup.
Two different numbers
Our score and the store score
Our 76.8/100 score comes from our public rules and the proof on this page. A store score comes from users in one store and country. For example, Google Play may show a new score when more people vote. Scores may also vary by country or device. We do not use store scores in our own score.
