It's The Beginner's Bible app from Zondervan. My 2 year old and 4 year old have asked for it every night since we got it. They like to take turns "turning" the pages.
The pictures are fantastic and very clear. The narrator is very easy to listen to - with a calm voice. The stories are well written and suitable for all ages of children.
The games are fun and interactive. It's a great way to review stories with your little ones after reading them with this app. We enjoyed everything about this app and would love to see more apps like this one.
