The verdict
A clean, no-nonsense way to do original-language word study from the King James text. Tap a word, see its Strong's number, the Hebrew or Greek behind it, and every other verse that uses it. It does one thing and does it well; for deeper lexicons or many translations you will still want a fuller study app.

Strong's Concordance — the long-standing index that assigns a number to every original-language word behind the King James Bible — has been a backbone of English-language Bible study since the 1890s. This app from Watchdis Group puts that whole system in your pocket and makes it tappable: read the KJV, touch any word, and jump straight to the Hebrew or Greek term it translates, its definition, and a concordance of everywhere else that word appears.
The appeal is simplicity. Where a full study suite can overwhelm, this app does the one thing a curious reader most often wants — "what did this word actually mean in the original?" — without a learning curve. Each word in the text is a link; the links lead to the Strong's entry; the entry shows the definition and the list of verses. You can read by book, search for an English word, or browse the concordance like a dictionary.
It is free, works offline, and keeps the interface deliberately spare — adjustable text size, a dark mode, and not much else to get in the way. It will not replace Logos or Accordance for serious exegesis, and it is built around the KJV rather than a shelf of modern translations, but for fast, friction-free word study it is one of the most approachable tools of its kind.
✓ The good
- Every word in the KJV is tappable — one touch jumps to its Strong's number and original-language meaning
- A true concordance: see every other verse where the same Hebrew or Greek word appears
- Greek and Hebrew dictionary lookups built in, so you can learn what a word meant before translation
- Works offline once installed — no account or connection needed for study
- Clean, distraction-free reading with adjustable text size and a dark mode
- Free, with a genuinely useful core rather than a stripped demo
✗ Watch out
- Built around the King James text — no modern translations alongside it
- Strong's definitions are concise glosses, not full scholarly lexicons (BDB, HALOT, BDAG)
- Not a full study environment — no commentaries, cross-references, maps, or notes syncing
- iOS only, with a utilitarian interface that prioritizes function over polish
- Strong's numbers can over-simplify — word meaning is shaped by context, not just a dictionary entry
Best for
- Readers who want to quickly check the Hebrew or Greek behind a KJV word
- Anyone learning to use Strong's numbers for word study without a steep learning curve
- Students and teachers who want a fast, offline concordance in their pocket
- People who already read the KJV and want to go one layer deeper into the original languages
Avoid if
- You want serious exegesis with full lexicons and commentaries (use Logos or Accordance)
- You read modern translations and want them side by side (use Olive Tree or YouVersion)
- You are on Android (this app is iOS only)
- You want notes, highlights, and reading plans that sync across devices
What Strong's Concordance is
Strong's Concordance from Watchdis Group is a focused word-study app for iOS. It pairs the King James Bible with Strong's numbering so that every word in the text becomes a link: tap it and you land on the Strong's entry for the Hebrew or Greek word it translates, complete with a short definition and a concordance listing every other verse where that same original word is used.
You can read straight through any book, search for an English word to find its occurrences, or browse the concordance as if flipping through a dictionary. The interface stays deliberately simple — adjustable text size, a dark color scheme to reduce eye strain, and offline access once installed. It is a single-purpose reference tool, not a full study suite, and that focus is the point.
Why a dedicated Strong's app still earns a place
Almost every big study app includes Strong's numbers somewhere, so why use a dedicated one? Because focus changes the experience. In a full suite, word study is one feature buried among dozens; here it is the entire interface, which means there is nothing to configure and nothing to wade through. Open the text, tap a word, and you are already looking at the original language and its other occurrences. For the specific, common task of "what's the Greek here, and where else does Paul use it?" that directness is the whole value.
It also lowers the barrier for people new to original-language study. You do not need to know how to open a lexicon panel or attach a reverse-interlinear — the linking is automatic and the path is obvious. That makes it a gentle on-ramp: a reader can start noticing how a single Hebrew word ties passages together, or that two English words translate the same Greek term, without buying or learning a heavyweight platform first.
Tap-to-original-language reading
The core feature is the tappable text. Reading the KJV, every word is a live link to its Strong's entry, so checking the Hebrew or Greek behind a phrase is a single tap rather than a separate lookup. The entry shows the original word, a transliteration, and a concise definition — enough to answer "what did this actually say?" in the moment, without leaving the verse you are reading.
This is where the app shines for everyday study. Hit a word that carries weight — "love," "propitiation," "hope," "world" — and you can see at a glance which original term stands behind it. It turns ordinary reading into something closer to a guided interlinear, and because it works offline, it is just as usable in a pew or on a plane as at a desk.
A real concordance, not just a dictionary
Beyond the definition, each Strong's entry functions as a concordance: it lists the other verses where the same Hebrew or Greek word appears. That is the feature that elevates word study from "what does this mean?" to "how is this word used across Scripture?" — letting you trace a term through a book or the whole canon and see its range of meaning in context.
You can also search by English word to find its occurrences, or browse the concordance directly like a reference volume. For tracing themes, comparing how a writer uses a key term, or simply settling a question about whether two English words share an original root, this is exactly the tool, and it does it cleanly.
Simple, offline, and out of the way
The app keeps its surface area small on purpose. There are reading controls — text size up to large, accessible sizes and a dark scheme — but no sprawling settings, accounts to create, or feeds to scroll. Once installed it works entirely offline, so your study does not depend on a connection.
That minimalism is a deliberate trade. There is no notes-syncing, no library of commentaries, no modern translations to compare — and if you want those, this is not the app. But for a fast, focused, distraction-free concordance that loads instantly and gets out of your way, the simplicity is a feature rather than a limitation.
Pricing
Free
Free
The full King James text with every word linked to its Strong's number, Greek and Hebrew dictionary lookups, the concordance of cross-references, English-word search, and offline use. The core study experience is free.
Strong's Concordance is free, and the free version is the real product rather than a teaser: the complete King James text with every word linked to its Strong's number, the Greek and Hebrew dictionaries, the concordance of cross-references, English-word search, and full offline use. For the core task — original-language word study from the KJV — there is nothing important held back.
Because the data (the KJV and Strong's) is in the public domain, there is no recurring cost or subscription pressure to worry about. The reasonable expectation is simply that an app this focused will not match a paid suite's depth of lexicons and commentaries — but for what it sets out to do, free is exactly the right price.
Where Strong's Concordance falls behind
It is tied to the King James text. The KJV-plus-Strong's pairing is classic and well-suited to this kind of study, but readers who work primarily in modern translations will miss having them alongside.
Strong's definitions are glosses, not full lexicons. They are a starting point; for serious exegesis you eventually want BDB, HALOT, or BDAG, which live in heavier study apps.
There is no broader study apparatus. No commentaries, maps, cross-reference chains beyond the concordance, or syncing notes — this is a reference tool, not a workstation.
It is iOS only. Android users need a different concordance app.
Word study can mislead if over-applied. A Strong's number tells you a word's range, not its meaning in a given verse — context, not the dictionary, settles that, and the app cannot do that thinking for you.
Strong's Concordance vs. Blue Letter Bible vs. Olive Tree
All three let you do original-language word study, but they sit at different points on the simplicity-to-depth scale.
Blue Letter Bible is the closest free comparison and goes deeper: alongside Strong's numbers it layers in multiple translations, several commentaries, interlinears, and study tools, all free. If you want the concordance plus a fuller study desk at no cost, Blue Letter Bible is the more powerful pick — at the price of a busier interface.
Olive Tree is the polished commercial reader: a beautiful multi-translation Bible with Strong's, split windows, and an a-la-carte store of premium lexicons and commentaries you can buy as you grow. If you want one app that scales from casual reading to serious study, Olive Tree is the better long-term home.
Strong's Concordance wins on focus. If all you want is to read the KJV and tap straight into the original languages and concordance — fast, offline, and free, with nothing else in the way — it is the most direct tool of the three. Many people keep it for quick word checks and reach for Blue Letter Bible or a paid suite when a question calls for real depth.
The bottom line
Strong's Concordance does one job and does it cleanly: it turns the King James text into a tappable concordance, so any word is one touch away from its Hebrew or Greek original, a definition, and every other verse that uses it. It will not replace a full study suite — no modern translations, no scholarly lexicons, no commentaries — and it is iOS only. But for fast, offline, friction-free word study, and as a gentle on-ramp to using Strong's numbers at all, it is one of the most approachable tools available, and it is free. Keep it for quick original-language checks and pair it with a fuller app when a question needs more depth.

Frequently asked questions
- Is the Strong's Concordance app free?
- Yes. The free version includes the full King James text with every word linked to its Strong's number, the Greek and Hebrew dictionaries, the concordance of cross-references, English-word search, and offline use. The core word-study experience is not paywalled.
- What does Strong's Concordance actually do?
- It lets you read the KJV and tap any word to see the Hebrew or Greek term behind it, along with a definition and a concordance listing every other verse where that same original word appears. You can also search by English word or browse the concordance like a dictionary.
- Does it include modern translations?
- No. The app is built around the King James text paired with Strong's numbering. If you want modern translations side by side, use a multi-translation app like Olive Tree or YouVersion alongside it.
- Is it good enough for serious Bible study?
- It is excellent for quick original-language word study, but Strong's entries are concise glosses rather than full scholarly lexicons, and there are no commentaries or cross-reference tools beyond the concordance. For deeper exegesis, pair it with Blue Letter Bible or a paid suite like Logos or Accordance.
- Is it available on Android?
- This particular app is iOS only. Android users can get similar Strong's word-study functionality from Blue Letter Bible or other concordance apps on Google Play.
- Can relying on Strong's numbers lead me astray?
- It can if over-applied. A Strong's entry shows a word's range of meaning, not its specific sense in a given verse — context determines that. Use it to inform your reading, not to override the plain sense of a passage, and check weighty conclusions against fuller resources.
