The translation used is King James. This was the version that I, and many others, grew up knowing simply as "The Bible," and has all the solemnity that you remember.
This app, like all the other free bible apps out there, is ad supported. The difference is, I promise never to interrupt the experience with full screen ads. So many other apps out there do, and it's really annoying (that's actually what led me to create this app). By downloading this app, you are helping to support an independent app developer, and a christian, to make a living.
If you would prefer a version without ads, you can find the paid version here:
Thank you for your support!
