The application is able to make a forecast of the weather phenomena that will happen in the next 2-3 hours based on a photo of the sky (it is advisable to take several in the direction the wind is coming from). It is also capable of detecting air pollution when smog is present during a clear day.
In addition, the app will give you interesting information related to weather knowledge.

This is a tool designed for use when there is no internet/satellite connection, which can predict for example if it will rain soon or if certain clouds will produce a heavy storm in the short term.

This is not a precision instrument but a tool to be used in a survival situation, which in case of total disconnection can be useful if you lack knowledge of meteorological interpretation.
