Ubuntu App Showdown rules

Rules & Eligibility

In order to make a level playing field for all submissions, any work on Original apps, and any porting work on Ported apps, must begin on or after the start of the App Showdown (Wednesday 26th February 2014), and must be submitted before the deadline (Wednesday 9th April 2014 at 23:59 UTC).

Apps must use one of the available languages supported by the Ubuntu SDK. This means apps can be written using C++ and Qt, Javascript and QML, HTML5. It is required to use the Ubuntu SDK for developing these apps, as we provide plugins and templates that make writing Ubuntu apps significantly easier.

Participants must be legally able to distribute the code used by their app as well as any dependencies, and both must use an open source license that allows Canonical and any other recipient of the code to distribute them.

Make sure you read the full terms and conditions.
