This app helps to reduce stress / depression and improve mental health.
We tend to often look at our phones (up to 50 times a day). On the other hand, stress became a bigger problem, due to the long working hours and the demanding modern life-style but researches shows that smiling always lifts up the mood and make the person happier. Thus, this innovative idea uses 'smile-recognition' instead of face-recognition to unlock the phone. When a user want to use his phone he will have to look at the phone and smile first, when the phone detect the smile it will unlock (this will happen only 5 times a day to let the user at least smile 5 times a day).
This method contributes to the mental health of the society, reduce anxiety and increase the productivity.
