Ive been using this app for a few weeks now and have not experienced any problems with it. I enjoy looking thru the different categories and find that there are quite enough selections to choose from just using the free app (which is nice because Im on a tight budget). I download a different one every few days, although if one wanted, they could download a total of 5 different ones per day. I find the pictures colourful and fun, and this app reminds me of my favourite graphics website (VladStudio) which also makes available fun, beautiful wallpapers.
