Canver is a paint application. It was developed for iPads, but should work (more or less) on any touchscreen device. You can try it live here.

It is just a simple client-side application based on HTML5 canvas, written purely in HTML, CoffeeScript and CSS.

Home Screen

For iOS devices, it is recommended to add Canver to Home Screen: then it feels more like a native app and works on full-screen.


    > git clone
    > cd canver
    > ./watch # a helper script to compile all the coffee on the fly


You'll need ruby and Bundler to run the tests. First, run bundle install. Once it's finished, run bundle exec rake jasmine and open the url provided by jasmine to run the tests. If you add any new files, make sure they are captured by the configuration file in spec/javascripts/support/jasmine.yml and watch file.

Known Issues

  • Does not support device orientation change.
  • Does not support image saving when added to Home Screen.
  • View is broken on smaller screens e.g. iPhone.
