Touching your face is bad. Treat your hands as if you have been chopping jalapeno peppers for a family of seven billion people. Just say: JalapeNO!

This app trains you to keep your hands away from your eyes, nose and mouth, by vibrating every time you bring your hands to your face.

Tapping the screen switches between modes: 1) active on the left wrist; 2) active on the right wrist; and 3) off.
