This app is not a scam. It actually does quite a good job at converting Word documents to PDF files. The only catch is that you cant load files directly into the application. You have to start from another application, such as an email attachment, and the option to load the file into this program will appear under the list of export options. From there, you are able to easily convert the word document to PDF file with one click.
It would be nice if instructions for using the app were available in English, but it was pretty easy to figure out how to use if you just start from another application. It sure beats paying six dollars for a simple task such as this. Thanks to the developers for a job well done!
