A gadget pair up with an app (think about your smart watch and its app) which can notify users when there are other humans approaching from the back. This is suitable for people who are often with their music on when walking or jogging on a very quiet street. I have a basic blue print for this idea and I am looking for passionate biz developers, designer sand developers who are into inventing human safety application. My goals are to make it easy and convenient to use, cheap to buy and most importantly, to protect and empower people especially for women.
