I use Logos on my PC, Tablet, phone and love it. As a pastor I have purchased a bundle for my studying but would also recommend this for the lay person who is just looking for a Bible app and some other basic study resources. We use another Logos related product called "Proclaim" to display song lyrics and Scripture to our church, and logos makes it possible to sync and follow along from your device.
One thing I appreciate about logos that I dont see on other popular Bible apps is the ability to Highlight specific words or phrases in the verse (as opposed to selecting the entire verse). I know its a small thing but I like it.
I use another app for my daily reading plan, but just discovered Logos has plans as well, so I plan on using Logos the next time I go through the Word.
I have had to contact Logos a few times for different trouble shooting issues, and they were always great to work with, and efficient in solving problems.
