Great App I use it on 4.4.4 (Paranoid Android) on an LG G2  it's fantastic. I primarily use the tumblr support. Which gives me strange wallpaper every time I turn wifi on  this is good  though occasionally inapropriate :) The only problem I have with it  is that the same wallpaper is often repeated if you try to force update the wallpaper  to get past some NSFW material that occasionally pops up. Great App though. Recommended.
