This app is superb. It is by far the most customizable bible app on the App Store when it comes to formatting. Paragraph kjv? Check. Precise margin adjustments? Check. Fonts, font sizes, margins, line spacing, indentation or not, HIDE VERSE NUMBERS for readability!, customizable colors, theme saving, highlights , bookmarks, customizable interface, and more.
It loads fast and has additional study tools available for purchase in app as well. You can view a reasonable set of translations and split the view to have up to four bibles side by side. The kjv can be used offline, but others may require the internet.
Has a great search function that works well. iCloud backup of notes, highlights, etc. Overall, it is my favorite bible app by far on iOS. The developer is very good with communication and support as well.
My only desire would be a "slightly" more advanced reading plan. It is simple and works well, but being able to pick a start date would be ideal (I don't always start a plan on January 1), and other apps have far more options. However, for what I use the app for, mainly a very readable and clean and book-like bible experience, the app absolutely excels. I can use other apps for a reading plan (such as ReadingPlan, which can launch this app for readings and is almost the equivalent awesomeness for a reading plan app).
Highly recommend this app. For actually reading the Bible, there is no better kjv app. Period.
