content: This App has enabled me to do things with PDFs that I couldnt do before such as edit PDFs add signatures upload or download PDFs to or from the cloud convert PDFs into a different format share documents with others with more options than before etc. I lack the technical knowledge to write a detailed review including specifications about this App. All I know is that it has made my life a little easier when it comes to paperwork  I thank God for anything that does that.
