I work for a media organisation in New Zealand, and we have created devotional apps for the android and apple (IOS) platforms.
One is aimed at youth (ish – ie 13-30) and the other at adults (ie 13-130 :P) – depending on whether you like Bob Gass and/or kiwi-ness, you might find these helpful.
They have a daily bible readng plan, a devotional in text format and in audio format.. please do not shoot me if you do not agree with the theological content, I know I sure dont.
The adult version is here
The contemporary version is here
If you download the apps, please dont forget to give a rating in the app store.
