Another day, another set of several hundred paid iPhone and iPad apps that are now on sale for free. BGR sifts through all of them for you each day in an effort to move past the junk and share only the most interesting apps in Apple’s App Store. And today, we have eight nifty apps for you that are worth a combined $50, but can all be had for free if you move quickly. These are paid iPhone and iPad apps that have been made available for free for a limited time by their developers. There is no way to tell how long they will be free. These sales could end an hour from now or a week from now
