Mozilla Appmaker helps you to design and publish your own Firefox OS -apps

Mozilla Appmaker is a pre-alpha -environment which works in your web-browser and lets you create and publish your own apps for Firefox OS. Take a look at: https://appmaker.mozillalabs.com/designer .

If you want to create a little app of your own, see first this YouTube-video, which explains what to do: http://youtu.be/RaRIdLgZTPI

As no programming skill is needed, anyone can create visible great apps. Maybe later it's possible to write and add some code to make apps do more complex tasks.
