I am currently designing an app website where I need to show video of the app in action. I came across this:

I'm just wondering... how did they do that?

I know that i can probably take a bunch of screenshots and then make an animated gif... but is there something out there that will actually allow me to capture a recording of the screen of my phone?

Thanks for any advice or a point in the right direction!
