# PDF Library eBook Reader vs EpubReader

The clearest difference is review sentiment: EpubReader at 100% against PDF Library eBook Reader's 60%. EpubReader also leads on in-app purchases (none vs 1). PDF Library eBook Reader's advantage is rating (4.3 vs 4.0) and update cadence (monthly vs every 3 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. PDF Library eBook Reader sells 1 one-off in-app purchase. EpubReader asks for nothing beyond the download.

PDF Library eBook Reader holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: PDF Library eBook Reader has 12 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 60% of PDF Library eBook Reader's written reviews are positive against 100% of EpubReader's, so the app with the better star average is not the one people write more warmly about.

PDF Library eBook Reader ships an update monthly, EpubReader every 3 months. The most recent releases landed on September 24, 2026 and September 13, 2026 respectively.
