Very glitchy now ???

Hey guys the last few updates have not really improved the ease of use, just made it more clunky with too many steps. I preferred it when it was simpler. The search function is really, really clunky and just keeps popping up before and after things all the time, and it takes forever. I usually have to tap things three or four times to even get them to work now. I do have an older iPad but it still should not be this slow, unresponsive and clunky. Awesome app regarding content, but just don't like all the pop up windows and extra steps. Too heavy. I liked it better when it was simpler. I'm sad to say that if this is how it is going to stay and if it is glitching purely because it is too heavy for my old iPad, I may have to find a different Bible app to use. Hope not. :)

My fav bible app, but could be better

I would like the option to purchase some versions currently only available online. I would also like to see the apocrypha made available from within BLB or a similar App. Likewise the Koran would be super useful to search out texts etc. the prefaces from each of the versions would likewise be useful.
Still my favorite after many years, and my first choice of study-help.

Great resource - Generally good Greek lexical notes

The Bible app is good. The lexical notes are good mostly and save a lot of time. However definitions of Greek Grammar are sometimes inaccurate (Consult Professor Daniel Wallace - Intermediate grammar course for precision). The lexicons are good also but sometimes skewed to the doctrines of Baptists. This is not objective. The sermons are mostly influenced by Baptists and some Calvinists (and possibly millennialist reasoning also - easily disproved by reference to Christ and the Apostles quotations of the Old Testament.
Nevertheless Blue Letter Bible is overall very helpful if used with discernment . 4 stars
