Is there an Android app which lets you lock all phone apps such as Chrome, FB, Instagram etc between a time period? So that the user can only use their phone for calling between that time period but all the other apps will be locked? Perhaps locked with a password which the phone user will not have. Similar to how in the 90s they had software for parental lock on computer.
What I am looking for is a way to stop kids from using their phone when they are in school or during bedtime.
