The text is always the same width in both portrait and landscape. Is this a bug?

No, it is not a bug. It is working as designed so that the text looks the same in both orientations and so that you won’t lose your place. It also leaves room on the right for the menu to coexist with the text in landscape, like you find in mail programs.

Can I put other texts into the AlphaRef Reader?

The AlphaRef KJV app comes fixed with the Bible. You can, though, create your own apps that have text that you provide. Please see the Homepage.

I live in the UK and can’t seem to download the app

The AlphaRef KJV app is not available in the UK at present for copyright reasons (it is in the public domain in the USA, etc., but not in the UK apparently.).

(More coming soon)
