Verdict
The clearest difference is ads: PDF Reader at none against PDF Viewer's shown. PDF Reader also leads on ratings volume (3.5K vs 5). On price, rating, update cadence and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. PDF Reader sells 10 in-app purchases, starting at $2.99 per month and PDF Viewer sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.5 for PDF Reader against 4.6 for PDF Viewer. That said, the two scores are not equally well evidenced: PDF Reader has 3.5K ratings behind it against 5, so its average is the more settled of the two.
PDF Reader ships an update every 2 months, PDF Viewer every 4 months. The most recent releases landed on September 24, 2026 and August 24, 2026 respectively.
