# PDF Expert vs PDF Reader

The clearest difference is rating: PDF Expert at 4.7 against PDF Reader's 3.5. PDF Expert also leads on ads (none vs shown) and update cadence (fortnightly vs every 9 months). PDF Reader's advantage is iOS requirement (9.0 vs 16.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. PDF Expert sells 10 in-app purchases, starting at $9.99 per month and PDF Reader sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

PDF Expert holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: PDF Expert has 216K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 46% of PDF Expert's written reviews are positive against 33% of PDF Reader's.

PDF Expert ships an update fortnightly, PDF Reader every 9 months. The most recent releases landed on September 24, 2026 and September 14, 2026 respectively.
