GIF ALERT: Full Width Sidebar

When design this app I wanted a sidebar that would take up the full width of the screen rather than leaving the previous screen partially seen to the right ala Facebook.

When sliding the view back or tapping the sidebar button the icon is fixed until it reaches a certain point then it gets dragged too.

Are there any other apps doing this with a sidebar?

You can download the app here if you like :)
