Many accidents happen because of people using their smartphone and not paying attention to their surroundings. This idea is about a smartphone app that warns people from danger or even prevents the usage of the phone. For example, when someone using the phone while driving, the app would then disallow the usage. Or when someone is walking around texting stuff and an obstacle is in the way, the app would warn the user. Technically, it is possible to use GPS to recognize a moving car or use the camera to recognize objects. Insurance companies could offer a discount in the insurance fee when people are using the app.
