content: Solid choice for the PDF software out there. It has a few annoying featuresspecifically nonremovable menu options that are for subscripiononly servicesbut overall is reliable and predictable. I like that it gathers all of the pdf files on my device without having to import them. On occasion there is a delay in rendering some pages but that is likely just a device issue. I recommend the app and keep it on all of my Android devices.
