What’s New

Version 1.3.3

We've added helpful prompts to make sure young explorers find all the dials, levers, switches, sliders and buttons on every page! We kind of liked letting kids discover that stuff on their own. But then we realized some kids were missing some of the fun. And that isn't cool. So we pointed out the fun stuff.

We've also made a bunch of little improvements. You probably won't notice. But . . . well . . . we did. So we made things better.

Great interactive book interesting for Maker Ed

I generally don’t take the time to review apps . .but this one got me really excited. I am an education professor and also an Apple Distinguished Educator and i only heard about this App when it was free for a day. its an interactive book that has appropriate reading strategies. I just spent about 30 minutes using it with my 4 year old nephew. He played it again and again and liked each of the machines. One thing that I thought was cool, he kept asking why the “marshmallows” reset on each screen. Auntie I made it small, why is it big again? it lead to a good discussion on how programmers make each page work.. (His daddy is a computer engineer).

The reading level is appropriate and it gives good feedback and allows each word to be spoken. The only bit of suggestion for improvement I would include would be to have something interactive on the last page or the the end page. My nephew was a little disappointed that everything was just “over” . .but he went back and started the book again.. (Maybe an interactive hug) ..

So who would be interested.. I think this is really appropriate for maker education as well.. i could see using it as an intro to a lesson on designing machines.

We still LOVE this app!!!

There is a reason this app is still getting featured by Apple.

Our kids are older now, but this story still has a place in our hearts. And we have friends with young kids who crack up at the cats and love playing with the machines. It's cool to see them enjoying it too.

My kids love the cats!
