My iPhone 7 says that the owner of this App needs to update it (and it hasn’t been updated in 3 years) before it will work with iOS 11. So what’s up with no updates? Paid $4.38 but can’t use it. Should have a disclaimer attached.

Lenny, thanks for your comment. We have now updated the app for iOS 11. In addition to it working on iOS 11, it also is now universal, so the one app will work on both your iPhone and iPad! Enjoy.

This tool's for you!

We raised our kids with the flash card and coloring book versions of this tool. How exciting to see these cartoons totally redrawn for a new generation and served up on a digital platform. There's simply no better or more fun way to learn what each book of the Bible is about. Finally a tool that gives us the map to find the Bible's answers to real life problems! Awesome!

Great way to learn the Old Testament themes!


Just loved this app! Creative way to learn the themes of each book of the Old Testament.
