I am curious if there is some sort of published business plan with regards to Logos mobile apps and Vyrso?
Why make Logos mobile apps for Android and IOS and then do it again with Vyrso?
Better than that, a discussion with the forum by the Logos CEO: http://community.logos.com/forums/p/33023/253547.aspx
The short answer:
1) the apps are geared towards different clientele* (some of which overlap)
2) the Vyrso app is a stripped down version of the Logos app and shares much of the same code (they are not reinventing the wheel)
3) the Vyrso app is geared more towards just reading / the Logos app is geared towards study
* The Vyrso store, when open later this year, will bring thousands more books to the Logos family. Many of these books will be "Christian Fiction" and other books which you would find at your local Christian Book Store.
