Note that there is something at work here that is as important as any of the gamifcation bits. The app is called "Bible" and there are literally hundreds of millions of Christians who read the bible who own a smartphone. So, it inherently is going to get downloaded. Also, the bible throughout time is among the most purchased, owned, and read book around the world. Phones and tablets are used for reading things, so it makes total sense that when you have a well made app called "Bible" that is free, has no ads, etc. it is going to get a pretty big install base by default. I'm not saying that the gamifcation stuff isn't working. I just know that being the most popular bible app across many platforms probably accounted for tens of millions of downloads in the first place.
