We’re starting off the new week with a roundup of the best paid iPhone and iPad apps on sale for free for a limited time. You know the drill: there are eight apps in today’s roundup but there’s no way to tell how long they’ll remain free. That means if you want any of them, you had better download them as soon as possible before these deals are done.

This post covers paid iPhone and iPad apps that have been made available for free for a limited time by their developers. BGR is not affiliated with any app 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 anyway, you will be charged by Apple. Some apps may have additional in-app purchases. Subscribe to our RSS feed to be notified as soon as these posts are published and you’ll avoid missing the sales we cover.
