Students will use a tool that will enable them to create their own mobile apps. Using a drag-and-drop interface, students will learn the basics of app design and coding to make apps they can share with friends and family. Taking advantage of all the features of a phone or tablet, like the camera, acceleromater, GPS, texting, etc, students can make exciting interactive apps.
By adding the phone features to the description, that gets them thinking of things other than just games. Hopefully you will have access to tablets or phones rather than just the emaulator?
