Just take a shot, choose a category and your image will be archived in your Dropbox. The best thing is that with only 3 clicks you can save your documents in a way that you will find them later on.

The App has only access to its own directory, therefore you don't have to be concerned about security. All your documents will be safe in the cloud.
They will be organized first by year, and then by the chosen category.

Hope this app will make your life easier.
