We closed out last week with a fantastic list of paid iPhone and iPad apps on sale for free. Well guess what: we’re picking up right where we left off. Monday’s post covering the day’s best premium iOS apps on sale for free includes several sweet offerings like one of the best iOS games of all time (Infinity Blade II), an app that transforms any iPhone into an accurate heart rate monitor, and plenty more. But as always, these sales could end at any time so be sure to check them out as soon as you can.

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 — obviously, the only thing we can guarantee is that they were free at the time this post was written. If you click on a link and see a price listed next to an app instead of the word “get,” it is no longer free. The sale has ended. If you download the app, you will be charged.
