Verdict
The clearest difference is rating: PDF Max at 4.5 against PDF Book Reader's 3.9. PDF Max also leads on ads (none vs shown) and ratings volume (1.2K vs 31). PDF Book Reader's advantage is update cadence (every 5 days vs monthly) and review sentiment (61% vs 35%). On price, in-app purchases, monetization model and device support 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 Max sells 10 in-app purchases, starting at $1.99 per 7 days and PDF Book Reader sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
PDF Max holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: PDF Max has 1.2K ratings behind it against 31, so its average is the more settled of the two. Written reviews complicate that: 35% of PDF Max's written reviews are positive against 61% of PDF Book Reader's, so the app with the better star average is not the one people write more warmly about.
PDF Max ships an update monthly, PDF Book Reader every 5 days. The most recent releases landed on September 24, 2026 and September 13, 2026 respectively.
