Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
