Yes Fellows. We have built our own Firefox OS application for the conference. It is HTML5 based, as any other Firefox OS Application. The great thing about it, is that you can also install it on your Android devices! You only need to have the Firefox browser installed.
Try it out!
A big thank you goes for Kelvin Cobanaj, who is the developer of the application.
For your curiosity, here are some screenshots.
If you want to download it, you can find it on Mozilla Marketplace.
