How we judge

  • The winners are chosen by the BUSY team: people from product, marketing, engineering and design.
  • There is no scoring system, so the decision is subjective. The judges consider how useful and original the app is, how clean its code is, how easy it is to use and how it looks.
  • Likes, views and shares of your posts do not affect the decision.
  • We judge the version of the app that is in your pull request on December 7 at 23:59 UTC.

Key dates

  • Contest opens at 00:00 UTC
  • Last day to enter, until 23:59 UTC
  • Winners announced on Discord

Who can enter

  • You must be 16 or older. Under 18, you need a parent’s or guardian’s permission.
  • You must live in one of these countries:
    • United States
    • Canada
    • United Kingdom
    • Australia
    • European Union, every member state

Why only these countries?

These are the countries where we can deliver prizes legally and pay the shipping, customs duties and import taxes ourselves, so the winner pays nothing on delivery.

Building the app with a friend who lives in one of them? The person who opens the pull request is the entrant, and the prize ships to their own address.
