Take part in the hackAIR summer photo contest

What is the contest about?

Send us a picture of the sky where you are currently spending your summer – using the hackAIR app. You’ll get a quick estimate of the air quality at your location – and the best pictures will win a hackAIR air quality sensor!

In your picture, we want to see what air quality means to you: be it good, bad or ugly, close to your home or far away. Where do you encounter good air quality? Where is it bad? Remember to always include a portion of the (cloudless) sky – so that we can give you an air quality estimate.

We are really excited to see your contributions!

Participating is super easy

Here is what you need to do:

  • If you haven’t downloaded the hackAIR app yet, do that right away here.
  • Find the right spot and timing for your photo!
  • Remember not to take pictures close to sunrise or sunset (as this makes it challenging for the platform to analyze your photo).
  • Here is more information about the sky photo feature of the hackAIR app


  • Every sky photo submitted through the hackAIR app between now and the end of August will enter the contest.
  • You can upload as many photos as you wish.
