The Adobe Acrobat Reader is another app you can explore if you are interested in a free PDF reader for iPhone and iPad. In free version mode, it supports reading the PDF on one page or scroll through mode and finding the content quickly with the searching text feature.

Similar to UPDF, you can take notes with annotating features like drawing, highlighting, sticky notes, etc.
