The Logos Bible app has many different translations available for reading and also has a text comparison feature you can use to compare different translations of a verse at a glance (see screenshot below). It also includes many Bible dictionary and commentary options.
My favorite part of this app is definitely the highlighting features. You can highlight by applying different colors, underlines, boxes, and even inductive study markups!
You can download the Logos Bible app for FREE on Android at Google Play or for your Apple devices at iTunes.
