Logos 7 and Accordance 12 are the two most highly recommended Bible softwares. If you own a Mac OS X or Windows PC, you should own one of these two Bible softwares. Bible study software helps any Christian desiring to study the Bible. Whether you study the Bible in a modern English translation or the original languages, you will find Bible study software to be a necessary tool.
In this article, I compare the key features of Logos 7 and Accordance 12 Bible Software. Because Bible software can be expensive, I want this comparison to help you decide which Bible software to purchase. So let the Logos vs Accordance Bible software review begin.
1. Bible Search using Logos 7 vs Accordance 12
Bible Search is the most important function of a Bible software. It should be simple yet powerful. Let’s compare the basic Bible search functionality in Logos 7 and Accordance 12.
Bible Search using Logos Bible Software
Bible Search in Logos is pretty easy. You select the range of search (Entire Bible, New Testament, etc.) and your preferred Bible translation. Then you type in the word(s) that you want to search.
Logical Operators in Logos Bible search
- AND: search for both words.
- OR: searches for either word.
- ANDNOT: searches for one word without the other.
Proximity Operators in Logos Bible search
- You can modify the proximity operators with X CHARS or X WORDS.
Unfortunately, there is no easy way to search for all forms of an English word. For example, I cannot type “sleep” and expect to find verses that contain “slept.”
Furthermore, Logos’ search speed is sluggish. On my laptop, it can take 3 to 8 seconds to do a simple word search (i.e. find all occurrences of the word “priest” in the entire Bible.)
Bible Search using Accordance Bible Software
Bible Search in Accordance is even easier than Logos. On the search bar, you can type verse references or words; Accordance will auto–detect and display the appropriate verses.
In your searches, Accordance allows you to select both the range and the scope. You can define the range of your search in Logos, but you cannot define the scope.
Scope Options in Accordance Bible Searches
Accordance allows you to toggle between exact word search and flex search. Flex search looks for all forms of a word. So if I use flex search for “priest,” Accordance will automatically find verses containing “priest,” “priests,” and “priest’s.”
Accordance even has a fuzzy search command. For example, if I type “faith hope love [FUZZY 1]”; Accordance will find verses that contain at least 2 out of the 3 words.
Symbols for English Searches
- ?: Any single letter
- *: One or more letters
- (): Groups like items together and sets priority.
Logical Operators in Accordance Bible Search
- AND: both “A” and “B”
- OR: either “A” or “B” or both
- NOT: word “A” but not “B”
- XOR: either “A” or “B” but not both
Proximity Operators in Accordance Bible Search
- FOLLOWED BY: “A” followed by “B”
- PRECEDED BY: “A” preceded by “B”
- WITHIN ?: “A” within “?” words of “B”
Accordance’s Bible search speed is blazing fast; search results are instantaneous.
Bible Search Verdict: Strong Advantage to Accordance
2. Word Study using Logos 7 vs Accordance 12
Bible word study is one of the most repeated steps in personal Bible study. You need to have the right lexical tools, but you also need to easily reference them. Bible software helps you discover the relevant information in your lexical tools. Let’s look at the process of Bible word study in Logos 7 and Accordance 12.
Word Study using Logos Bible Software
Logos has two useful guides for Bible word study.
Logos Bible Word Study
When you type an English word into Logos’ Bible Word Study guide, it will return the following:
- A list of hyperlinks to all the Bible dictionary entries of that word.
- A translation pie chart of all the Hebrew words that are translated to the English word in your selected English translation.
- A translation pie chart of all the Greek words that are translated to the English word in your selected English translation.
- A list of short phrases that include your English word. These phrases are mapped to Logos’ Topic Guide.
Many beginner Bible students love using this module to aid them in Bible word study.
Logos Exegetical Guide
Logos’ Exegetical Guide is a more powerful tool designed for Bible exegetes. The components of Logos’ Exegetical Guide are fully customizable, but the component most pertinent to Bible word study is the “Word By Word” module.
This module analyzes each word in a particular verse. You can show every word or limit the module to just display the original language lemmas that appear a certain number of times in the Bible. For each word, this module lists the following:
- Original language lemma
- Audio pronunciation
- English Transliteration
- Brief lexical definition
- Morphological parsing
- Syntactical function (i.e. subject, prepositional object)
- Bible sense as defined by Logos’ Bible Sense lexicon
- List of hyperlinks to entries for all your lexicons that contain the word lemma.
I feel that Logos’ Exegetical Guide is the most complete tool for word study for Bible exegetes. It is second to none.
One additional note: Logos has a few lexicons that are still not available in Accordance. As an example, Moulton and Mulligan’s Vocabulary of the Greek New Testament is one lexicon I wished I had on Accordance.
Word Study using Accordance Bible Software
Accordance has nothing equivalent to Logos’ Exegetical Guide and its “Word by Word” module. However, you can get most of the same information using a few quick steps.
Accordance Instant Details
Hover over a word in an English translation with Strong’s tagging gives me the following:
- Strong’s number
- Original language lemma
- English transliteration
- Morphological parsing
I can also get the syntactical function if I hover over a word in the Hebrew OT or Greek NT that has syntax tagging.
If I press the command key while hovering, I see the full entry in my default Greek and Hebrew dictionary, and I see the number of occurrences the lemma is used in the Bible.
Accordance Research Command
If I right click on a word, I can enable the Accordance Research command. Research is a way to search a subset of your entire Accordance library. Library subsets I might use to complete a Bible word search include the following:
- Greek lexicons
- Hebrew lexicons
- Bible Dictionaries
- All Tools
Accordance Word Search
If I right click on a word in an English translation, I can search the English word or the “Key Number.” Searching by key number completes a word of the corresponding Hebrew or Greek lemma.
If I right click on a word in the Hebrew OT or Greek NT, I can search the word as the (1) Lexeme, (2) Inflected, or (3) Root.
Accordance’s Instant Details, Research, and Word Search provides me the same information as Logos’ Exegetical Guide and “Word by Word” module. Unfortunately, many steps are required to compile all the data; with Logos’ Exegetical Guide, I just type the verse reference, and Logos displays all the information in seconds.
Word Study Verdict: Advantage to Logos
3. Syntactical Study using Logos 7 vs Accordance 12
Syntactical Study using Logos Bible Software
Propositional Outlines in Logos
One of Logos’ newest features is the Old and New Testament propositional outlines. Mark Keaton and the Logos team formatted the Bible and created these propositional outlines. They divided sentences into phrases and clauses. The entire text is indented, and each phrase and clause is given a label to name its function. This is a great starting point for my syntactical analysis.
Next to Logos’ Exegetical Guide, this is probably my second favorite feature in Logos.
Syntax Databases in Logos
- Andersen–Forbes Dataset for Hebrew OT
- Cascadia for Greek NT
- Greek NT and Dataset: SBL Edition
- Opentext.org for Greek NT
- Lexham Syntactical Greek NT
I use Andersen–Forbes and Cascadia heavily as my syntactical dataset references. I think both datasets are excellent.
Syntactical Study using Accordance Bible Software
Accordance has nothing comparable to Logos’ propositional outlines.
Syntax Databases in Accordance
- Accordance Old Testament Syntax Database
- ETCBC Hebrew Syntax and Morphology Database
- Accordance New Testament Syntax Database
Accordance’s Greek New Testament Syntax database was recently completed. The Hebrew Old Testament Syntax database created by Robert Holmsteadt is almost complete. Accordance 12 also introduced the availability of the ETCBC Hebrew Syntax database.
The gap between Logos and Accordance is closer, but at this time, Logos’ syntax datasets and syntax tools are still significantly ahead of Accordance.
Syntactical Study Verdict: Strong Advantage to Logos
4. Complex Searches using Logos 7 vs Accordance 12
We had covered basic Bible searching earlier. There are times when you will want to do a more complicated search. Most of these searches are in Hebrew and Greek.
The searches may include multiple criteria; they will include conditions based on specific morphological and syntactical tags of the biblical text. This feature is used most often for serious Bible research. Even teaching pastors who do engage in weekly sessions of exegesis for sermon preparation will only occasionally perform complex searches. That being said, let’s still compare the complex search features for Logos and Accordance.
Clause Search using Logos Bible Software
This functionality is unique to Logos, and it is based on the following datasets created by Logos:
- Greek NT: SBL Edition
- Lexham Hebrew Bible
You can perform searches looking at the following:
- Entities: person, place or thing.
- Semantic Roles
- Syntactic Roles: subject, object, adverbial clause
- Predicate Verb by lemma
For example, I can search for all verses in the New Testament where Jesus is used as the subject, and Peter is the direct object. Clause search can even find sentences when a pronoun is used and not the proper noun. There is no comparable feature in Accordance.
Morphological Search using Logos Bible Software
Like Accordance, you can search by (1) Lexeme (2) Inflected, and (3) Root in morphological search in Logos.
For Greek nouns, you can specify (1) case, (2) number, (3) gender, and (4) degree.
For Greek verbs, you can specify (1) tense, (2) voice, (3) Mood, (4) Person, and (5) Number.
The morphological tagging of the biblical texts in Logos and Accordance is similar but not identical. Overall, Logos has more original language Biblical text and other writings with morphological tagging.
Syntax Search using Logos Bible Software
The syntax search includes about 15-20 prebuilt constructs. As indicated beforehand, even though Logos’ syntax datasets are excellent, the usability of the syntax search is abysmal. I actually think Logos should rebuild the syntax search interface completely.
Search Bar in Accordance Bible Software
Accordance’s search bar was discussed earlier when I reviewed the Bible search function. It is simple to use, and it is powerful. Accordance’s search bar interface is flawless. It can do everything Logos’ Bible and Morph search can do; but it is easier to use, and it is faster.
Constructs in Accordance Bible Software
Constructs is the most powerful feature in Accordance Bible Software. You can create the most complex morphological and syntactical searches, and the interface is surprisingly easy to use.
Even though I prefer Logos’ morphological tagged resources and syntax datasets, Accordance’s Constructs feature propels itself as the better tool for complex searches.
Complex Search Verdict: Slight Advantage to Accordance
5. Logos Passage Guide vs Accordance Info Pane
Passage Guide in Logos Bible Software
Logos Wogos’ Passage Guide is a great first stop when studying a Bible passage. Simply enter the reference of your Bible passage, and Logos’ Passage Guide will give you a summary of all the Logos library resources relevant to your Bible passage. The passage guide displays the following:
- Hyperlinks to all commentaries you own that include your passage.
- Cross references and parallel passages.
- Ancient writings and journals that discuss your passage.
- Hyperlinks to all outlines of your passage.
- List of biblical persons, places, things and events referenced in your passage.
- Word graph of interesting words in your passage.
Info Pane in Accordance Bible Software
Accordance’s Info Pane is the analog to Logos’ Passage Guide. The info pane lists the following:
- Hyperlinks to commentaries and study Bibles you own that include your passage.
- Cross references and parallel passages
- Hyperlinks to Bible dictionaries for passage topics, biblical persons, and places.
- Word list of your passage
- Grammars that reference your passage.
- BHS and NA28 Apparatus
Logos’ Passage Guide vs. Accordance’s Info Pane: Slight Advantage to Logos
6. Topical Study using Logos 7 vs Accordance 12
The bulk of my effort is studying Bible verses and passages. But occasionally, instead of studying a specific Bible passage, I will study a topic like tithing. Let’s compare the tools Logos and Accordance have for topical study.
Topic Guide in Logos Bible Software
When you enter the name of a topic in Logos’ Topic Guide, you see the following:
- Hyperlinks to all your Bible dictionaries with entries about your topic.
- List of key verses and relevant passages about your topic.
Factbook in Logos Bible Software
Factbook is unique to Logos. Like Logos’ topic guide, Logos’ Facebook includes Bible dictionary entries, key verses, and relevant passages. But Factbook includes a lot more:
- List of Biblical Senses taken from Logos’ proprietary Biblical Sense Lexicon.
- List of resources to cultural concepts taken from both ancient writings and Bible dictionaries.
Topical Study in Accordance Bible Software
Unlike Logos, there is no topic guide in Accordance. Accordance’s main tools for topical study are Nave’s topical Bible, the NAS Topical Index, and the Topical Textbook.
I can use the Research feature and search through a subset of my entire Accordance library on a specific topic. For example, I can type the name of a topic and search through all my Bible dictionaries and theological works.
Topical Study Verdict: Slight Advantage to Logos
7. Timeline and Atlas using Logos 7 vs Accordance 12
The timeline for Logos Bible software contains over 10,000 elements and events. However, I find the readability and usability of Logos’ timeline to be poor.
The timeline in Accordance Bible software is superb. It is beautiful. It is easy to use. Although there are far fewer events and entries in Accordance’s timeline, I have never used Logos’ timeline once I purchased Accordance’s.
Accordance’s atlas is better than Logos’. Furthermore, Sacred Bridge is an exclusive library add–on for Accordance. It is not available for Logos. Many consider Sacred Bridge to be the best Bible Atlas available today.
Timeline and Atlas: Advantage to Accordance

- Anchor Bible Dictionary (6 volume)
- New Interpreter’s Dictionary of the Bible (5 volume)

Library Add-Ons: Strong Advantage to Logos
9. Mobile Apps for Logos and Accordance
Logos and Accordance have created mobile apps that allow you to read your library resources and perform basic library and Bible search. Let’s take a look at each one.
Logos Mobile App 5.8
Logos has mobile apps available for both the iOS and Android platform. Even though the interface is not entirely simple, the core functionality of the Logos mobile app is very good.
Features that I want to highlight:
- Search your entire Logos library or your custom collections.
- Perform simple flex Bible searches in any Bible translation.
- Mobile versions of Passage Guide, Exegetical Guide, Bible Word Study and Topic Guide.
- Mobile version of Logos Bible Atlas and Text Comparison modules.
- Browse and read any library resource without downloading the entire resource. You can still download resources to your phone or tablet to improve speed.
Accordance Mobile App 2.4
The most important fact to note is that Accordance Mobile is only available on iOS devices. At this time, there is no Accordance Mobile app available for Android.
Accordance’s Mobile App has a simpler interface. It is pretty easy to have a split pane view and view two resources simultaneously. You can quickly toggle to link both panes. The interlinear function in Accordance Mobile is very easy to customize. I much prefer it to Logos’.
The search bar has all the same basic functionalities as the search bar on the desktop application. You can search grammatical tags, use all the search commands and symbols, and you can set range, scope and context. You can given toggle on and off Accordance’s Flex Search.
You must download a resource before you can use it. Easy Install and updating resources is very similar to the desktop application.
The library in Accordance Mobile is much better organized, since it creates folders for English Tools, Greek Tools, Hebrew Tools, and Reference Tools automatically. However, you cannot create custom collections like you can in Logos.
If you prefer iOS, Accordance has the advantage. But if you use an Android phone, you have no solution with Accordance. Only Logos has an Android app available for the mobile platform.
Mobile App Verdict: Slight Advantage to Logos
10. Technical Support for Logos and Accordance
The technical support for Accordance Bible Software is superb; the Accordance community, likewise. I can ask a question on the Accordance forum. Usually a member of the community or a member of the Accordance team will answer my question within 1 calendar day. This includes Saturdays and Sundays.
When I e-mail a question to the Accordance Support, I get a personalized response usually within a day. I cannot imagine getting better support. I feel like every member of the Accordance looks at their Bible software as a labor of love.
The technical support for Logos Bible software is adequate but less personal. I generally receive generic responses with hyperlinks to help files on their webpage; sometimes, they do not address the problem to my satisfaction. I definitely feel like the company that supports Logos is bigger, less personable, and sometimes less helpful.
Technical Support: Slight Advantage to Accordance

Logos 7 vs Accordance 12 Bible Software: Which One to Get?
- If you do not own any Bible software and looking for a first purchase, Accordance is the Bible software to get. It is more affordable. It is easier to use. It is faster. You will not outgrow the power of Accordance.
- If you are looking for the ultimate Christian electronic library, you should purchase Logos. Just about every possible digital library resource is available in Logos.
- If you already own Logos, I think you should stay with Logos. You know how to use Logos, and you have invested financially in your library. There is no compelling reason to throw away the time and financial investment.
- If you already own Accordance, the reason to add Logos is to use their proprietary features: propositional outlines, Andersen–Forbes and other syntax databases, Logos’ exegetical guides, New Testament Use of Old Testament module, etc. Logos also has many library add-ons and digital resources to build your ultimate Christian library. Many books and most obscure works are not available in Accordance.
