I own a new patent called MasteryPro and simple put it allows an electronic device to be interrupted and forces the user to answer questions by multiple choice, fill the blanks etc before they can get back to using the device. We have developed hundreds of modules from all the k-12 main subjects to the Bible. We will make MasteryPro free with a couple of modules and then charge for the other modules. The parent would load the system and pass code it for their child. It is also a great system for adult learning. One bite at a time!
