There's an example of a fullscreen icon there, and you can just open it in chrome and then choose the 'add to desktop' option inside Chrome's menu.
Otherwise you could write your own app using Bluetooth LE and the Android development SDK (which could be a bit of a steep learning curve if you haven't done anything already), or could use DroidScript - there's a post on that here: http://forum.espruino.com/conversations/297507/
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
Yes, absolutely!
Probably the easiest option is to use a Web Bluetooth website - there's some info on it here: http://www.espruino.com/Puck.js+Web+Bluetooth
