A very useful app.

I have been using this app for about two years now. I am able to save pictures and videos in different folders. Then I can delete them pictures from my iPhone. If I want to I can send them back to the iPhone. Pretty simple to use. You can even run the slideshow with it.
I have never had a crash with this app, it is a very fast and friendly. I highly recommend this app.
