I am new to IOS. I understand the 5 finger crumple to view open apps, and how to close apps from there.
- How/Why does IOS work this way?
- Should I 'NOT' care how many apps are 'open'?
- Will IOS close them as needed?
- Should I keep an eye on ram/resource usage?
Well, short form: There's no "Close" menu item because there's no menu. In general you shouldn't care about how many apps are open, because in general the number of apps that are open is 1. In a relative handful of cases there are little stub help programs left running on behalf of other applications, but the reality is that iOS only runs a single interactive process at a time and that's whatever one owns your screen at the moment. iOS suspends them when they are switched out, and bumps them from memory *if* the memory is needed by the active application.
In particular, do not read too much into the app switcher bar that shows up at the bottom of the screen when you perform the right gestures. It is a list of programs that have run recently provided to give you a quick way to get back to them without going to the home screen. Contrary to popular opinion and a bit of marketing, the apps shown in there are not running.
