Advanced Task Killer may have been the first of the Android task killers, but it is by no means the best. Why? Continue reading after the break. As you can see from the above picture, Advanced Task Killer (ATK) presents you with a list of running apps when you first open it. This is where the problems begin. While other Android task killers give you a choice of which apps you want to kill, ATK automatically selects all of them, meaning that if you want to kill just one, you'll have to manually unselect all of them. While it is true that if you long press on an app's title then you'll get an option to kill just that app, it is a hidden feature without any clues indicating that you should do this. As you can see, the long press menu also allows you to select or unselect the app, although you can also do this much more easily by tapping the app's name shortly, switch to the app, which you could also do more easily by pressing the home button of your device, or ignore the app so that it won't be selected by default. Again, this is useful, but long pressing each app's title and telling it to "ignore" could take a while. But the biggest annoyance of all is that there is no option at all to place a widget on the homescreen allowing you to quit apps quickly. One would expect that this would be available from the settings menu, but there are only two options there: With nothing to set it apart from the competition other than its expensive $4.99 price tag (there is also a free version of the app, but it is littered with ads), it's hard to recommend ATK over something like TaskPanel or TasKiller.
