I find it easier to concentrate with reading a real Bible.
My app is e-sword which is great for looking things up or having different translations, but I still like the real thing :D
A paper bible is way better... Well this more of a take on I had a sermon prepared but it went down the knothole... The newest version is I had a sermon prepared on my tablet, Ipad or whatever but I forgot to bring my charger... Yeah my dog eared KJV is better... No batteries or electricity required!... Don't you just love to turn the pages?... I do!.. Brother Glen:D
Been in the field, sweating my tail off in New Mexico. Got a beat up Zondervan leather touch NIV (1984 version for those who keep track :Tongue ), that's been through a dozen or so countries with me. It was a gift from my wife's grandma.
Depends on what I'm doing. For continuous reading, which I do a lot of, I read on my kindle. I have many translations and study editions on Kindle, as they are very cheap to acquire. The adjustable font size is just easier on my aging eyes in the very early morning, and the textual notes are easy to pop up. For study, I have several paper Bibles that I can mark and make notes in. It's easier to flip around in a paper Bible, but I am thankful we live in an age where there are choices.
I prefer to use an actual Bible, I have tried to use an app but for some reason I just can't do it. I guess I like having the Bible in my hands, I pretty much keep a Bible in every room just about, and even in the car. :p
