Studying the Bible shouldn’t be hard. NKJV Bible by Olive Tree equips you with easy-to-use Bible study tools and resources so you can stop skimming Scripture and get answers—for free.

Here are 4 ways you’ll be set-up for studying God’s Word:

That’s right, you don’t need a WiFi connection to access your Bible, audio Bible, or any other Bible study tools. You could be in the middle of the Amazon or on top of Mt. Everest. If your phone is working, so is your offline Bible app.

God has been speaking to His people, through His people, for thousands of years… and that takes some research to understand! This is why we provide 1000s of resources (free & paid) to help you go deeper into God’s Word—because studying the Holy Bible shouldn’t be hard.

And when we say “resources,” we mean:

Not only do we implement unique features into our app, but we do it with style. Our favorite is the split-screen window: The Study Center. You can use the Resource Guide tab to access any of the resources available in our app and read them right alongside the Bible of your choice. It even does all the hard work of tracking with you, verse by verse. Studying the Bible just became the easiest it has ever been.

Want more highlighter options? That’s fine!
Pick your own color, thickness, and change it to underline instead.

Have trouble reading small print? Increase the font size!

Reading at night? Change the theme to be easier on your eyes.

Want to listen safely while you drive? Turn on drive mode!

You can save your favorite passages, drop a book ribbon, create a note, add tags, and sign up to receive a daily Bible verse. Best part? Your highlights, notes, and resources sync between all your devices.

If you’re wondering about our different English translations, this app comes with NIV, ESV, KJV, NKJV and more. Speak a different language? No problem! We have Bibles in Spanish, Portuguese, Chinese, French, and others.

We also have other popular translations available for in-app purchase!
Here are a few:
-The Message (MSG)
-New Revised Standard Version (NRSV)
-New Living Translation (NLT)
-The Passion Translation
-Christian Standard Bible (CSB)
-New American Standard Bible (NASB)

Our passion is inspiring you to connect with God and His Word through technology. Not only is this a free Bible app, but we also have 100s of free resources—all day, every day.

There’s no need to spend lots of money on paper resources that sit on a shelf. By investing in digital resources, you will be able to get the answers you need wherever you are—even offline. Stop flipping pages aimlessly and get Bible study tools that do the hardest work for you!

We have all your favorite Bible study tools and resources available for purchase.

Frustrating update

I have been using this app for about 4t years. It has been useful in keeping notes and grouping related passages together with the feature called tags Unfortunately after this last update when I open tags and go to a saved topic that I have spent many hours saving ... it opens fine but when I close the verse instead of being able to see the next tag it goes to the last open screen and not the next tag . I then have to start over and open several windows to get to the next tag .... very frustrating. It’s like having notes saved in your bible for years and then you get up one morning and someone has move them to a different page ... this happened a couple years ago to .... This was especially frustrating as my wife was sick and passing and I wanted to share some verses with her but had a lot of trouble looking them up.

Useful Bible App

Updated Fall 2017
I do not enjoy this app as much as I used to. The latest version no longer has the ability to be read in landscape mode, the mode I prefer. Also, Olive Tree is constantly trying to sell more books. I'm constantly getting notifications that are really just advertisements. The latest edition even has a cart at top and center. I just want a few versions of the Bible on my phone, not a whole pastor's library. It's still a useful app, just not as good as it was.
Original Review:
I have no other app to compare it to, but I enjoy this bible app. My favorite feature is the search feature - it's like having a full concordance in my hand. Also, if I highlight a verse in one version, it's highlighted in all - good for favorite verses. Now if I just highlight a few words, they are only highlighted in that version. Also, I can flip from one version to another and stay at that verse. I can also switch to a commentary and see the comments on the passage I am reading and switch to my atlas and be at the part pertaining to the passage. Very helpful. I still have my old fashioned study bible, but I keep this handy for searches and of course it is with me everywhere I go - and I don't need wi-fi, it's all on my iPod touch. And when I upgraded to an iPhone, it was easy to make the transition with regular cloud backups with Olive Tree. Great Bible app.

Whada’bout the rest?

This is, in this reviewer’s opinion, the most well thought-out mobile Bible app—especially for tablets, but still very usable on a smartphone.

The ‘Resource Guide’ that ‘automagically’ collects all of the pertinent information in a user’s resources/library for a particular passage is what really distinguishes it from other Bible apps when combined with a number of scholarly and semi-scholarly resources as part of a user’s library of resources.

Some very good scholarly original language resources are available to go with a variety of ‘tagged’ original language texts.

The latest version7 revision has some GUI improvements to the ‘look-and-feel’ of the UI.

The main question that i have relative to this last comment is, as this review title states, “Whada’bout the rest?”, meaning, version 7 of the Olive Tree Bible Reader is *not* yet available for some of the particular versions of Olive Tree Bible Reader (e.g., NASB Bible+ and the Greek-Hebrew Original Language apps—to name just two). The best that this reviewer can determine is that it seems that only 3 of the 8 or so versions of this app are available in version 7. My other installations of other versions of the app are stuck in the past (last maintenance/feature release of version 6).

When does Olive Tree expect to release version 7 of their other ‘flavors’ of this app?

Developer Response ,

The 7.1 update will only be released to our three main apps (Bible by Olive Tree, NIV Bible by Olive Tree, and NKJV Bible by Olive Tree). If you are using one of our other apps, we recommend downloading one of these three apps.

These apps have all of the features you currently use and will continue to be updated/maintained. You will also be able to access all of your resources and annotations by logging into your Olive Tree Account within the updated app.
