# PDF Reader vs EPUB Viewer Pro

The clearest difference is rating: PDF Reader at 4.3 against EPUB Viewer Pro's 3.5. PDF Reader also leads on ratings volume (3.9K vs 13) and update cadence (every 2 months vs every 5 months). EPUB Viewer Pro's advantage is iOS requirement (13.0 vs 15.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

PDF Reader holds the better App Store score, 4.3 against 3.5. That said, the two scores are not equally well evidenced: PDF Reader has 3.9K ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 77% of PDF Reader's written reviews are positive against 84% of EPUB Viewer Pro's, so the app with the better star average is not the one people write more warmly about.

PDF Reader ships an update every 2 months, EPUB Viewer Pro every 5 months. The most recent releases landed on September 23, 2026 and September 21, 2026 respectively.
