CoffeeScript At Once

What app do you use for killing time?
Social Game? Thats fun.
But "Web Programming" is not such a bad way to pass the time.

CoffeeScript At Once is a simple web development environment on iPhone.
CoffeeScript makes JavaScript less difficult. For examle, downsizing the number of typings. Its better for iPhone or iPad.

You can also use external library like jQuery and Processing.
Of course, plain JavaScript is working, too.

Enjoy web programming without personal computers!
