As long as you open the app when you restart your phone, it should track fine in the background.
Also, removing apps from the app list in iOS is a bad habbit that you should avoid. This does nothing but reduce the performance of your device, and cause issues with how apps perform. iOS handles apps in and out of memory automatically, making sure you don't run into those kinds of issues. User intervention isn't necessary.
Maybe we are talking about different things? I know I've used the wrong nomenclature before. I asked a friend (big time Apple guy) how to 'Jailbreak' an Android tablet, that didn't go over well LOL.
So, when I hit the home button twice and all those apps show up that I scroll through sideways, you just leave all of them there? Flicking up on these to close I should avoid? Wouldn't multitasking be difficult with all that clutter on the screen? When my Daughter is done with an app she closes it. It's second nature for her to close apps when she is done, this would pose a problem if it needed to be there to monitor wifi.
Anyway, I'll try out that app
Just FYI, "headless" app is a seldom used term that doesn't actually mean much in the real world anymore. Blackberry uses it to describe apps without a visible UI which would normally be known as services, but Blackberry's apps are far too bloated to be services.
My biggest 'headless' app on my phone only occupies 3MB out of the 2G ram and <0.1% of CPU. Not an expert but it doesn't seem 'bloated'.
