Just to clarify. You are only eligible for the $250 after you add your app to the Tizen Store. The steps to take are:
Get your app scored on appbackr from the Scira page
Wait to receive your score and cash incentive. If the app does not pass, you'll receive feedback telling you how the app needs to be changed.
When your app gets a passing appscore, we will send you the app re-packaged for Tizen.
Sign up as a seller on the Tizen Store and add the app at seller.tizenstore.com.
When you receive the confirmation from Tizen that the app is approved, we will arrange for payment.
