Really good
I recommend this app to people who don't like to be notice by other people, have many secrets. While you a using this app, you'll notice that is app is really nice and comfortable. First, you can select passwords so that other people can't see your photos. Also, you can select the color, name, password of your file. Let's say that you made a file called 'Justin Bieber'. First, you select the color of the file, and then you can also made hundreds of Subfiles. You can do the same thing in subfile as well. Second, the file transfer is nice as well. It is fast. You can send the photo in Facebook and Twitter too.
