This app is easy to use once to learn how to do it. I had to view the app in iTunes in order to figure it out. I wish the instructions were on the app itself. I looked into other programs to merge .pdfs and the cheapest I found was $49 and was hard to use. I then realized there must be an app for that and found this one. I do wish that it had a way to connect to Dropbox but I get the results I want.
