This app shows the the possible concentration of aluminium in your area.
Obviously there is no easy way to measure the aluminium concentration in the atmosphere. Your mobile device does not contain any technology that allows this app to count particles in the air around you. Despite these limitations this app tries to calculate a possible, but not necessarily correct value. A very complex formula is used to make an educated guess possible results of scientific measurements in your area.

How good are the measurements?
All results calculated by this app, are at best very good guesses. We have got quite some years of experience when it comes to measure air quality and particle concentration in the atmosphere. We used this knowledge to develop this app. Nonetheless we can not guarantee that our guessed values are correct. After all the primary goal of this application is to motivate scientific discussions about the conspiracy theory about chemtrails.
