phonegap, you're so amazing!
I just built my first non-hello-world app: https://github.com/dglittle/phonegap-timer
you can download it here: https://build.phonegap.com/apps/505560/builds
"phonegap build" compiles the app for all the phones in the cloud, I didn't install any software on my own machine. To test it locally, I just loaded my html file in chrome — of course, there was one line chrome couldn't run: navigator.notification.vibrate(1000), which is meant to vibrate the phone for one second, but other than that, the app is literally a single html file, with some standard includes like jquery and bootstrap and phonegap's own api (oh, and a small config.xml file)
