Very good app  specially with the NASA APOD plugin. The wallpapers are terrific  and I love the fact that the wallpaper stays blurred in the background until you double tap  at which points it comes into focus for a few seconds. Great touch  very slick. Highly recommended. *EDIT* I've noticed for several months now  the app has become buggy. Wallpaper doesn't update properly  the app crashes  and sometimes loads half a page... I stuck with it for months  hoping for improvement  but no luck. Sadly  I will no longer be using it. A shame  really.
