There's a smartphone app for pretty much anything you can think of these days, but that doesn't mean there isn't room on the market for more. However, we don't want you to design an entire app for this reward (although you can if you'd like, we'd be very impressed!), we just want you to design the user interface (UI) for one.

This fictional app can be for any purpose you like, but it must meet the following criteria:

1. It must be safe for work;

2. It must serve a clear purpose, but can be unrealistic;

3. e.g. a social platform for people living on Mars

4. And you must show at least two different screens of your app.

Submissions should come in image form, but can be either a physical or digital sketch, or you can use a design tool such as Figma, Photoshop, or Canva. Submissions will be judged on the creativity of the idea, quality of the designs, and thought behind the layout.
