Gutenbergz Inc. wanted kids to learn more about technology, so they created Gadgetarium - an Interactive Children’s Book About Technology. The app was fully funded through a Kickstarter campaign in 2013 and has just been released for iOS.
Gadgetarium takes children, 6 years and older, through the history of technology; from the creation of the wheel to radios, microscopes, and more. The inventions can be viewed as 3D models that can be played with to learn more about them, and users are guided through their discoveries by a boy and his pet pug.
Gadgetarium also offers the ability to mix different gadgets to create new inventions to help foster curiosity and creativity. You can pick it up for $1.99 on the App Store.
