I tried this app out of necessity. The app I had been using failed to load after I installed their upgrade. They never fixed it... just decided it was time to abandon the iPhone 3. So I tried BLB... what a great app! Better performance, more study tools, no registration requirements to use them, no nag screens to write a review. I get the strong impression that BLBs main focus is to promote Bible study and not allow their software to get in the way!
