This is the ultimate bible online study

Tremendous bible resource in every way, just start exploring and be sure to click on a verse and click the one in the middle of menu and you will be able view Greek and Hebrew and explanation of all words (that choice is: Concordance/Interlinear); and so much more, all ad free. It is truly amazing. I started using this app over 7 years ago. The desktop edition is also great. For this app:They keep improving on what is already great. Example: choice for you to have the chapter read aloud for you, or the whole of the book within the 66 books of the Bible. Just about every translation of the many English translations are available. Also includes Thayer’s in depth original and amazing words in Bible I continue to learn about the root meanings through this tremendous resource that the brilliant geniuses of the development team make available when you go to a verse in linear concordance and tap any word you will get
Hebrew and Greek of word it even pronounces it for you and click at bottom of that page for the Thayer selection which opens up a whole realm of authentic text Insight- when you see it you’ll get what I mean -
hard to describe depths of this and for each word. I’m not an employee of this remarkable non profit, may I recommend supporting it. Also fully available on your web browser. iPad version is also dynamic and outstanding as well.

Amazing study feature removed with latest update

Hello. I’ve been using your app for years and it’s one of the best study tools available on iOS. I was extremely surprised to see in the latest update released this week that in the interlinear you NO LONGER can see where a Strong’s number is used for the corresponding Hebrew or Greek word you want to study. For instance there are several words used for wisdom in proverbs. I used to could pick a verse, click on the word for wisdom and see all verses where the word was used. That I can still do but it NO LONGER shows in the list of scriptures where the Strong’s word I’m researching was actually used. Sometimes the word wisdom can be used twice in the same verse but 2 different Hebrew words are used. Well I no longer can see which is used for the word I’m currently studying! I just know it’s one of them but I can’t tell which one unless I actually go into that verse and study it separately. This is a major feature loss and I’m shocked this was removed. Please let us see the Strong’s numbers in the list of usage verses again. Thanks!

Thanks for your response. You can see the Strong’s numbers for all verses using a word AS LONG as you go to interlinear in the KJV version. I wish it was with any translation like before but at least you can still access it. This is still the best bible study app on the store!

Developer Response ,

Hello and thank you for leaving a review. The Blue Letter Bible apologies for any inconvenience you are having with the app. Please know that the format of the Interlinear changed with revision 2.70 of the app to match more closely that of the main BLB web site mobile responsiveness interface and the Android mobile app interface.

This format change provides for both forward and reverse Interlinear and is now provides a more consistent interface of information across platforms. As you tap on the individual Strong's numbers within the view you will find the Outline of Biblical Usage, Strong's Definitions, Lexicon information and Concordance information as you scroll.

If you have any questions please don't hesitate to contact the ministry and a staff member will respond. Please use this link to contact us (

Sola Scrriptura • Solus Christus • Soli Deo Gloria

The Word of God is my barometer for life; for spiritual life. The Blue Letter Bible enables me to have His Word available at times I don't have my Bible. It is truly a "user friendly" App. Blue Letter Bible also has a great website. I've been blessed with the opportunity to meet some of the Blue Letter Staff on a couple of occasions and from them, learn much more about the App and about Blue Letter's ministry. It is obviously to make God's Word available to more souls. It is a God honoring ministry • Soli Deo Gloria. The App contains many wonderful features: a) Search; b) Ability to highlight text; c) Background color/text color change; d) Audio read; and e) Scroll feature to name a few. I have found the App's features to be consistently reliable. The Blue Letter App doesn't contain a lot of extraneous, options (or programs) to distract from the pure Word of God as do some Bible Apps. In essence, The Blue Letter Bible provides one with the opportunity to have The Word in an unclouded format. In a format in which one needn't be concerned with the potentially misleading opinions of man. I love the purity of The Word of God and, with the assistance of The Holy Spirit, drawing nigh Him through His precious Word. When I consider The Blue Letter Bible App, I am made mindful of the monicker "Sola Scriptura"! Thank you Blue Letter Bible for your wonderful App!
