About this app

INDEPENDENCE NOTICE

SkyCalm is a private, independently developed app by Fermento Digitale. It does not represent and is not affiliated with, endorsed by or authorized by any government or political entity. It does not provide or facilitate government services.

Did you search for “chemtrails” because a line in the sky looked unusual? SkyCalm starts with the question and compares available data to show when a flight and known atmospheric conditions are compatible with an ordinary condensation trail.

With your permission to use location, the app finds aircraft in your local area and connects air traffic, flight altitude, temperature and humidity aloft.

With SkyCalm you can:

• see aircraft detected near your position;
• check available flight altitude, direction and distance;
• compare temperature and humidity aloft;
• visualize condensation trails that may be observable above you;
• understand why some trails disappear quickly while others spread like cirrus clouds;
• read an illustrated guide to contrail science;
• share reports and text messages with the local community.

RESULT LIMITATIONS

SkyCalm does not chemically analyze or identify a photographed trail and does not replace direct sampling. Its result is an educational estimate based on available flight data and atmospheric models. Flight availability depends on network coverage, and not every aircraft may be visible.
