love the Blue Letter Bible app.
I allows me to copy and paste verses easily. It is extremely good when
I need to search a word or phrase in the entire Bible or part thereof,
but most of all it serves as a fantastic reference source.
I can click on a verse, and see it in a dozen versions. Or I can see
that verse in the greek or hebrew and get the definitions for that
word, and also see every time that word has been used throughout the Bible.
It's an extremely useful app, although a little clunky and slow at times.
Available for iPad and iPhone.
