Moment is an iOS app that automatically tracks how much you use your phone or iPad each day.
The app allows you to set limits if you’re using your phone too much and it can send you notifications when you have gone over your daily limit. You can even use the app to force yourself to stay off your phone all day if you do go over your limit.
Moment Family is also a great tool to control your families use of screen time where you can set a limit on your own phone for the entire family. A great time for the family to be screen-free would be at dinner.
