# PDF Book Reader vs PDF Reader Pro

The clearest difference is review sentiment: PDF Reader Pro at 100% against PDF Book Reader's 61%. PDF Reader Pro also leads on in-app purchases (none vs 2). PDF Book Reader's advantage is update cadence (every 5 days vs every 4 months) and rating (3.9 vs 3.6). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. PDF Book Reader sells 2 in-app purchases, starting at $3.99 per month. PDF Reader Pro asks for nothing beyond the download.

PDF Book Reader holds the better App Store score, 3.9 against 3.6. Both are backed by a comparable volume of ratings — 31 and 8 respectively. Written reviews complicate that: 61% of PDF Book Reader's written reviews are positive against 100% of PDF Reader Pro's, so the app with the better star average is not the one people write more warmly about.

PDF Book Reader ships an update every 5 days, PDF Reader Pro every 4 months. The most recent releases landed on October 4, 2026 and September 28, 2026 respectively.
