I stumbled upon this app recently and just love it. It takes you through the whole Bible, sections at a time, with an Audio expanation of what you're reading. It's really cool, and has become part of my daily reading plan of God's Word. These audio productions are very professional and bring clarity to some of the most difficult Bible passages, especially Revelation. I found that section truly enlightening.
They manage to make their explanations entertaining, a little humorous, and very relevent to our walk with Jesus. It helps to explain the relevance of Scripture in our daily lives. It's really quite good, and whether you like to read along or just listen, this is well worth the 'Free' it costs to download. :)
