There are now more active cell phones than humans. (?) The camera lenses of cell phones can detect cosmic rays. An app has been created that stores such detections in a data base. The app has been used in Iceland, Uzbekistan, and Uganda. There is no apparent practical use, it is for "outreach and education."
