where is it?

I downloaded this and when I clicked on it to open, nothing happened. What's up??? I finally saw that it was on the toolbar. Well, a little instructions would help. I really wanted this for my iPhone, not my computer.

Simple. Does what it says, but a bit too simple...

It could use SOME more options.. Like maybe an ability to NOT kill certain apps? Do this, and you'll have a perfect product here! (:

Great app...

… unless you want to waste time 'Force Quit'-ing every single app that's gonna stay there for ever. Value your time? Get it now.
