How to enter

There are 3 steps to entering the Challenge.

  1. Developers need to create .wgt files from their HTML apps.  Developers can do this with our handy HTML5 Guide to Porting to Tizen in our Tools section.
  2. Register on the Tizen Seller Store and add your app to the Tizen Seller Store: The one field that you need to add is to add "appbackr" in the Comments for Validation Team field. This allows appbackr to track your app’s status and expedite your validation process.
  3. Register for the challenge, with your .wgt file by filling out the submission form.

If you didn't add "appbackr" to the Comments field, include your developer DeepLink and app Content ID. Instructions to locate that information are here.
