THE IMPORTANCE OF THE SKY
Simple just take an image of the sky within the app, adjust the image to fit with your current mood and upload the mood sky with your location. Both platforms will then automatically be updated, to reflect the average mood in that area.
The sky is an entirely neutral object and since the mood report is less about the image itself and more about emotions, the sky was an obvious choice. The important aspect of the app is to acknowledge how you are feeling in that instant and adjust the sky to match. Whether it being light and optimistic, moody or dark and dramatic. No words needed.
