High School Teacher Creates New Educational App

   Anyone have an iPad, droid, or a technology that has apps yet? If so then how many of you know how to create an app? The article Article From eClassroom News  is all about how this one high school math teacher was able to create an app for his students. The app he created had allowed the students to be able to add comment to any kinds of files like to PDFs, PowerPoint, etc.This kind of app is really helpful to students of every grade.
   If I had known about to make an app then I probably would've made one for my classroom. It is hard to find games or fun activities for the students to engage in and at the same time help them learn. If I can I would make an app of an animal food chain for science or a quick restaurant game to help the students with their math when it came to paying the bill. This is what I would use an app for. Other than making an app for anything else... I wouldn't because I am lazy.
