But the apps themselves are closed...depends on what you want, to actually close the apps or to clear the list of recently used apps.
Got a tip for us?

Is there a quick way to close all open apps?

Yeah, for that purpose, aside from some jailbreak tweak, the only real option you have (at least so far) is to swipe away the apps yourself whenever you want to clear them out.
Excellent suggestion to read up on this. The paragraph below is from the iOS App Programming Guide (emphasis mine):
Because the iOS virtual memory model does not include disk swap space, apps are more limited in the amount of memory they have available for use. Using large amounts of memory can seriously degrade system performance and potentially cause the system to terminate your app. In addition, apps running under multitasking must share system memory with all other running apps. Therefore, make it a high priority to reduce the amount of memory used by your app.
There is a direct correlation between the amount of free memory available and the relative performance of your app. Less free memory means that the system is more likely to have trouble fulfilling future memory requests. If that happens, the system can always remove suspended apps, code pages, or other nonvolatile resources from memory. However, removing those apps and resources from memory may be only a temporary fix, especially if they are needed again a short time later. Instead, minimize your memory use in the first place, and clean up the memory you do use in a timely manner.
I simply prefer to not have my system dispatch low-memory warnings and rely on the apps to clean themselves up in the allotted five seconds, only to possibly bounce back into a low-memory condition (rinse, lather, repeat).
If you don't remove apps from your recently used app list and don't have problems, great! But resetting an iPhone to launch Real Racer or X-plane, or Settings opening slowly on my kid's iPod that has many items in the recently used app list is an indication that Apple is correct when they say that the amount of free memory has an impact on system performance.
You do know you're reading developer notes, not instructions to the user? The point is, the system, and the apps designed for it, are designed to manage, request and release memory themselves - they do not require the user to do this for them. The situation the previous poster described where the system would slow down when only 2% memory is free - does not happen in IOS, since if IOS needs more memory it releases it, simple as that.
The five seconds you're referring to, are not related to the low-memory condition.
When the user clicks the home button, the app, that is in the foreground, is moved to the background and gets 5 seconds to save everything and make sure it is in a state where it can be closed without losing any data. After the 5 seconds the app is being suspended without any further notice by iOS.
The moving of a suspended app out of the memory is a matter of microseconds, few milliseconds tops. Even with a close all button you'd lose more time closing apps manually than you spend "waiting" for freeing up memory.
That's like saying the apps come back when you re-open and close the app.
My solution still stands
Spoken like a marketing exec. Too often I have heard that very comment bandied about, usually by someone who last wrote a single line of BASIC multiple decades prior too get his Commodore to do something "cool", only to have said project run months and dollars over budget simply because VERY few things in software only take a "few lines of code."
What?That's like saying the apps come back when you re-open and close the app.

And restarting doesn't clear out the list of recently used apps, which seems to be (at least the main part of) what the OP wants to be able to do quickly.

It was a joke
No one coding for even 5 years would ever make a statement like that when it comes to complex software designed by a team, especially an OS. Certainly not as far as making sure it doesn't affect anything and doesn't negatively affect the user. There's more than just plain coding that goes on when it comes to anything like that.
However all that is moot as Apple doesn't think that functionality is needed and in fact specifically doesn't want to provide that to users.
i agree that it's not always that easy, but it would be the same as a gesture of swiping up on all of the apps. very simple.
Yes, I'm reading where Apple describes a scenario where system performance is impacted. People keep repeating how it's supposed to work. Apple describes and I see cases where it doesn't.
I'll give you the 30 minutes to create the button in the framework used for development, but then you have find and link and call the termination code for each app, which will be done in loop. To hit all logic paths that can occur I would estimate will take many ten s of lines of code if not hundreds lines.
There shouldn't be a reason to close apps .... Unfortunately iOS memory manager isn't working very well so far, and ram isn't promptly released when needed.
For that reason I verified that closing unused apps helps a little bit.
