We all know the stress of enjoying the weekend but mail is still sent to your iphone. Very annoying sometimes. One still needs the phone for other things but one is not wanting to see mail.

To create less stress during the evening or during the weekend I would welcome a preference where one could change the "app being online" I would call it Airtime :-)
Example:
App online and working: Mo,Tue, Wed, Thurs, Fr 08AM-17PM
App offline and not working: Mo-Fr 17PM-08AM
App offline: Weekends

App offline: when a certain speed is reached (car driving) and one can either choose : I'm behind the wheel > app not working or I'm a passenger > app working

Let it be possible to choose days, dates, times.
