IOS and Anfroid mobile app

The idea is an app that when turned on turns the smart phone into the old nokia or flip phone screen. You can only make calls and take calls, play the basic snake game at most. Text messages can be sent but you have to type them out long ways like before. No pictures or videos. There is a timer in the app that returns phone back to normal with a secret code or Face ID. This is for the person that wants to tune out of smart phone apps and distractions but still is available for phone calls and texts that are necessary but doesn't silence the phone. Too many of us are using valuable relaxation time or family time working and glued to our phones. It can serve as an alternative to turning phone completely off or leaving at home for all types of users. Parents can even use it to restrict phone access of their minors without taking the phone away.
