Although there are many iOS and Android Apps for Studying the Bible, it’s hard to say these apps are 100% portable for many reasons. For instance copying a verse from your Smart Phone or the tablet into the Word Processor in your Laptop or PC actually require an additional app and some extra effort. Which is why it’s always a good idea to take a Portable Bible Study Software in your iPod, USB flash drive or portable hard drive which you can run in Windows. One can argue why you need a portable version when you can install the software in a Laptop. The idea is a portable version doesn’t limit you to your own PC.
