My group and I have a free Christian app on the Android Market (we plan to extend this to Apple etc..) called ''Moodverse''. You simply enter your mood and it gives you a verse/ scripture matching that mood. As of now, we got two Bible versions integrated on the app, KJV and ASV (we couldn't use NIV, due to copyright issues). When it comes to the different versions of the bible, I always thought KJV and NIV were the most used versions but I'm getting different responses from people. The response seems to be linked to geographical location. For instance most Americans would go for ASV and so on.
My question is this, what version of the Bible would you all suggest we use for our app? Which is more preferable?
