Yes, says the developer: closed it works like a small iPhone, open like an iPad, and half folded the study window takes half the screen.

About Olive Tree Bible
Olive Tree is a Bible study app from Gospel Technologies, on the App Store since 2009. Alongside the Bible text it opens commentaries, study Bibles, dictionaries and original-language tools in a split window, and its Resource Guide shows notes, articles and maps related to the passage you’re reading. Notes can be anchored to verses and filed by topic, and everything downloads for reading offline. The app is free, with books and resources to buy.
The developer says Olive Tree treats the Duo’s cover as a small iPhone and the open display as an iPad, and that when the phone is partly folded with the split study window showing, the window resizes to half the width of the screen. We haven’t seen it running.
