Verdict

The call

The clearest difference is rating: PDF Max at 4.5 against PDF Reader Pro's 3.6. PDF Max also leads on ads (none vs shown) and ratings volume (1.2K vs 8). PDF Reader Pro's advantage is in-app purchases (none vs 10) and review sentiment (50% vs 35%). On price and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

PDF Max holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: PDF Max has 1.2K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 35% of PDF Max's written reviews are positive against 50% of PDF Reader Pro's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

PDF Max ships an update monthly, PDF Reader Pro every 4 months. The most recent releases landed on October 22, 2026 and October 24, 2026 respectively.
