Not a problem with it yet. But can we have a password lock to protect important documents we may get from email? But other than that works just as it says it does.

I bought this on a whim, figuring if it didn't actually work I'd only have spent a dollar. Much to my pleasant surprise, this program does exactly what it advertises it will do - it extracts files from WinRAR archives. The design of the interface is not fantastic - it took me a moment or three to figure out how to actually get to the files I'd extracted. You need to be extracting files that the iDevice knows how to use - in my case, a few JPG files to use as backgrounds/wallpapers, but as long as you can do something with the files - process them in some app on your iDevice, then this will work as desired. I don't know about advanced features - password protection, etc, but for the basic issue: extracting files, well, this program did that and very easily, no fuss, no muss. I installed it, clicked on a download link for a file with a .RAR extension in Safari, and when Safari prompted me to use another program to open the file, I chose RARExtractor and it opened the archive. Then, I figured out the interface and went to the contents of the RAR, and tapped on a JPG, which allowed me to save it to my photostream, and from there I could make it a background.

Despite its simple look, the layout is utterly terrible. The "About" button is where the "Back" button is supposed to be, and you switching from the normal to the editing mode is annoying. Furthermore, I often cannot open a file. Switching from the storage of another app to this app works, but it just isn't showing the file!

I find this app very easy to use. It also allows you to send extracted files by email which is a plus.
