Have you ever seen the night sky? If yes, how does it look like? What can you see? How bright is it? Are the stars visible? These are all questions that can be answered by looking at the sky with your own eyes, and using the phone as a light meter. That's what this app is for.
It allows you to take a picture of the sky with your phone, and then get the brightness of the night as measured by your phone. It doesn't need any special equipment, you can use your smartphone. It is a very simple app, easy to use and understand. It's free to download.
It is an excellent way to contribute to a world-wide citizen science project. All the information is used to calculate the world-wide light pollution, and to create a map of it.
