SESH! I love my SESH daily reader. It is almost always exactly what I need to hear
There are some recovery apps but I cannot mention names here and they are not official NarAnon material - I think they have more to do with AA.
I also created my own Recovery Journal where I write down sayings or quotes that I like. I also paste in brochure pieces or responses I get at online meetings if I want to hang on to them. I look at that a lot, even when I am not adding anything to it.
Here is a link to the online NarAnon webstore, there are descriptions of each piece of approved lit there: http://www.nar-anon.org/Nar-Anon/Web_Store.html
