content: By far the most userfriendly and consistent .pdf reader Ive ever used for Android. Easy user interface for nontechies like myself. Makes it simple to download share edit and save .pdfs. The only .pdf reader app Ive used that downloads and opens files consistently and without popups or ads Doesnt cause my phone to freeze or become slow or glitchy. Its now my default .pdf reader for my Android S21.
