content: Adobe had been a useful tool when it comes to viewing pdf files and I cant recommend it more. It is also widely used appsoftware across different platform. However when it comes to editing pdf files its a bit complicate as you have to use another Adobe app. Its kinda inconvenient but the app does as it says so I aint gonna complain. But if there was a way of rearranging duplicating copying and removing pages would make more convenient. This is with free access of course.
