The children (3 and 6) were excited to try the new book.
However, while the children seemed to enjoy the book, I had a hard time keep my child's attention with the story. I Think this was a combination of the layout of the book, and the story itself.
The book is layed out with two story pages on the screen, split down the center just like an actual book. This meant there were two separate 'play' buttons, one for each half of the screen, and two separate animation buttons. While my eldest was able to figure it out quickly, the younger daughter, who usually has no problem using e-books found it difficult to figure out which button to push, resulting in either missing pages or going in the wrong order. There should realistically be just one page, one play button. There also shouldn't be a need for a animation button as the children would figure out to simply just push the picture to get an animation.
As far as the animations, the youngest enjoyed them, but she also enjoys doing-ing the spring that is behind the door. The eldest however, gave up on the animations as they really weren't worth doing. A wing flap here, a flutter there, some random disjointed sound clip here.
The story was a bit long for the youngest but with a little coaxing, she stuck it through. The eldest breezed through it and seemed to enjoy it, but when asked later what she thought of it, all I got was a 'it was okay'. My personal opinion is that the subject matter was a bit awkward as teaching a child to get a revenge on an older sibling is by humiliating them, isn't something I would willingly choose to teach my kids. Impressionable children may take this to heart. A younger sibling may incorporate the idea of being bullied by older siblings into their worldview, even if completely inaccurate, because they just read a book about how that is what older siblings do.
If I had to base my decision on just this one story with no knowledge of any other books offered, I probably wouldn't continue with the service. But as I was able to look at a few covers of the other books that were offered, I got a sense that this might have just been a miss.
I usually do sit with my kids as they read and will do book programs with them as we can share that moment, but as modern times dictates, realistically I can't always be there to walk my kids through complex book layouts. So, the problem with the layout would be a big stopper. If this was fixed and it was one page on the screen at a time, I would consider the trying the service longer.
Overall, I give it a 5 out of 10. Straight up average. Not the greatest thing I have used, but definitely not the worst. The kids sorta enjoyed it for a while, but I don't see either of them sticking with it long term and probably moving onto easier services.
