Carrell vs Logos, Accordance and Olive Tree: An Honest Comparison

November 10, 2026

Logos, Accordance and Olive Tree are the best-known Bible study programs, and each has been developed for decades. Carrell is much newer and is built around a different idea. This page compares the four so you can tell which fits the way you study.

We make Carrell, so read this with that in mind. We have tried to be fair: the other three are described from their own published pages and prices as of November 2026, and we say plainly where Carrell falls short. Prices change, so check each company’s site before you buy.

The short answer

• Logos if you want the largest library of commentaries and reference works, deep original-language tools, and you prepare sermons or study at seminary level.
• Accordance if original-language searching is central to your work and you prefer to buy a library once rather than subscribe.
• Olive Tree if you want a clean, familiar reader on every device, including Android and Windows, and a licensed translation such as the NIV or ESV.
• Carrell if you want a fast reader with your own notes, recorded sermons and photographed study pages in one library beside the text, on a Mac, Linux, iPhone or iPad.

Two different ideas of Bible software

Logos, Accordance and Olive Tree are built around a library of books. The app is the shelf, and much of its value comes from the commentaries, dictionaries, study Bibles and translations you add to it. That model is excellent for reference work: open a passage and the commentaries on it are a click away.

Carrell is built around your own material. It has the Bible text, but what it gathers beside each verse is what you have written, heard and photographed: notes, sermon transcripts and pictures of handwritten pages or slides. It has no store of books to buy.

Neither idea is better. They answer different questions: “What have scholars said about this verse?” and “What have I learned about this verse, and where did I write it down?”

Platforms

• Logos: Windows, macOS (14 and later), iPhone, iPad, Android and a web app. Not on Linux, though a community project runs it under Wine.
• Accordance: Windows and macOS on the desktop, with mobile apps for iPhone, iPad and Android.
• Olive Tree: Windows, macOS (14 and later), iPhone, iPad and Android.
• Carrell: macOS 11 and later, Linux (64-bit x86), iPhone and iPad, with an Apple Watch app for recording sermons. No Windows or Android app.

If you use Windows or Android, Carrell is not an option today. If you use Linux, it is the only one of the four that runs natively.

Price

• Logos has a free version. Paid plans are Premium at $9.99 a month, Pro at $14.99 and Max at $19.99, with yearly prices lower, and books and libraries can also be bought outright.
• Accordance sells collections. The least expensive full copy, the Basic Starter collection, lists at $49.90, and new accounts get a 90-day free trial. Larger collections cost hundreds of dollars or more, with upgrade pricing between them.
• Olive Tree is free to download with several translations included. Books are sold individually, and optional subscriptions run from $2.99 to $19.99 a month.
• Carrell is free for the reader, seven translations, search, highlights, notes and bookmarks, with no limits. Pro is $5 a month or $54 a year and raises the allowances for Ask, sermon transcription, photos and storage.

Translations

This is where Carrell is most limited. Logos, Accordance and Olive Tree sell licensed modern translations such as the NIV, ESV, NKJV, NASB and CSB. Carrell does not offer them today.

Carrell includes seven public-domain translations: the KJV, WEB, BSB, ASV, Young’s Literal, Darby and Webster. Pro adds more Bibles read online through API.Bible, including editions of the Geneva Bible and the Douay-Rheims, Greek New Testaments, the Septuagint and the Hebrew Westminster Leningrad Codex. You can also import translation files you own, in USFM, OSIS, Zefania and SWORD formats, on the Mac and Linux. If your church reads from the NIV or ESV and you want that exact text, one of the others will serve you better.

Commentaries and study tools

Logos and Accordance are far ahead here. Each offers thousands of titles, original-language lexicons and grammars, morphological searching, and tools for word studies, timelines and maps. Olive Tree offers a large store of study Bibles and commentaries with simpler tools.

Carrell has no book store. When you ask a question, Ask draws on original-language words, a lexicon, cross references, people and places, and public-domain commentaries, and cites each source. That is useful for everyday questions, but it is not a research library, and it is no substitute for Logos or Accordance in seminary work.

Notes, sermons and your own material

All four let you highlight and write notes on verses. The differences are in what else you can keep.

• Logos has notes, highlighting and sermon-writing tools for preparing your own sermons.
• Accordance has notes and highlighting attached to verses.
• Olive Tree has notes, highlights and tags that sync across its apps.
• Carrell records sermons on iPhone, Apple Watch, Mac or Linux and, with Pro, transcribes them with an outline and the passages read. It reads photos of handwritten notes and slides and links them to the verses they mention. All of this appears in the margin beside the passage the next time you read it, and Ask can answer from it.

If you already have notes elsewhere, the Carrell desktop apps can import them from Logos, Accordance, Olive Tree, YouVersion, Blue Letter Bible and e-Sword, and export everything to Markdown or JSON.

Speed and reading

Large study programs carry a lot, and they can take a while to start and to search a big library. Carrell is a native app that does less, and it is quick: showing the first page takes about 15 ms of work, and searching the whole Bible takes under 2 ms, so results appear as you type. If most of your time is spent reading rather than researching, that difference is noticeable.

Where Carrell falls short

• No licensed modern translations such as the NIV or ESV.
• No library of commentaries or reference books to buy.
• No Windows or Android app.
• It is in beta, so features may change.

Using more than one

These programs are not exclusive. Many people keep Logos or Accordance for research and use a lighter app for daily reading and notes. If that suits you, Carrell can sit beside your existing software: import your notes once, then read and keep new notes, sermons and photos in Carrell. Our guide to free Bible apps for the Mac covers more options.
