Just as the title says are there any apps for my daily devotions.
Try Xiphos or gnome-sword (this is for very older installations) for a complete solution, including the option to install daily devotionals (though nothing beats reading the Bible as the Spirit leads in a free way ;)).
P.S. they are the same program, but Xiphos is the renamed newer version.
There is also bibletime if you use QT/KDE or just want variety.
If you want to install extra Bible translations, Bible maps, and devotions, then add the crosswire.org sources within the program, and download as many as you want ;).
Hope that helps ^^!
