The excellent Video Time Machine app for iPad (and iPhone) is free this weekend, down from it’s standard $2.99 price.

This is one of my all-time favorite iPad apps. I did a review of Video Time Machine for iPad it last year and said of it at the time:

This is one of those very rare apps that grabs you from the first moment that you open it, and just keeps you gripped and fascinated on every visit to it. It’s the equivalent of a great book you can’t put down, you just keep wanting more.

It was also included in our list of Best iPad Apps of 2011. Here are some of its key features:
