All PDF Reader, PDF Viewer is a straightforward solution for users who need reliable PDF viewing with basic editing capabilities. The app excels in its primary function: opening and rendering PDF files quickly, which is ideal for reviewing documents, manuals, or e-tickets on the go. For marking up documents, it includes a set of practical annotation tools. Users can highlight important text, draw shapes, and add handwritten notes or typed comments directly onto the page. This makes it suitable for students reviewing lecture notes or professionals providing feedback on a contract draft. The interface is generally clean, prioritizing the document viewer with annotation tools accessible from a toolbar.

However, the app's strength in simplicity can also be a limitation for power users. Reviews indicate that while the core annotation features work well, advanced options like adding digital signatures or complex form filling are not its focus. Some users report that managing a very large library of PDFs within the app can feel less organized compared to dedicated document managers. File support is broad, handling documents from local storage, cloud services, and email attachments. Overall, it serves its stated purpose effectively, providing a capable viewer and annotator without overwhelming users with complicated menus or unnecessary features.

I use this daily to review work PDFs. The highlighter and note tools are right there and work every time, though I wish organizing files was a bit easier.
