Verdict

The call

The clearest difference is rating: PDF Max at 4.5 against pdf's 4.0. PDF Max also leads on ads (none vs shown) and ratings volume (1.2K vs 17). pdf's advantage is review sentiment (49% vs 35%) and iOS requirement (16.0 vs 18.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. PDF Max sells 10 in-app purchases, starting at $1.99 per 7 days and pdf sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

PDF Max holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: PDF Max has 1.2K ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 35% of PDF Max's written reviews are positive against 49% of pdf'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 every 5 weeks. The most recent releases landed on October 17, 2026 and October 12, 2026 respectively.
