I wrote that app last year. It comes with a web dashboard to follow activities of evaluation of the Tsetse flies population in regions in D.R.C. where sleeping sickness is endemic.

The screen that you see in the picture is a simple compass showing you where is a fly trap that you placed on the river a few days before. It’s a bit “Tsetse Flies Go”. People often do not have any network connection during this type of work, so, we went for something that works offline, without maps.
