Verdict

The call

The clearest difference is monetization model: PDF Splitter + PDF Merge at free with in-app purchases against PDF Pro's subscription. PDF Splitter + PDF Merge also leads on review sentiment (88% vs 60%) and iOS requirement (13.0 vs 17.0). PDF Pro's advantage is ratings volume (6.9K vs 139) and rating (4.7 vs 4.5). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. PDF Pro sells 12 in-app purchases, starting at $1.99 per month and PDF Splitter + PDF Merge sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

PDF Pro holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: PDF Pro has 6.9K ratings behind it against 139, so its average is the more settled of the two. Written reviews complicate that: 60% of PDF Pro's written reviews are positive against 88% of PDF Splitter + PDF Merge's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

PDF Pro ships an update every 2 months, PDF Splitter + PDF Merge every 3 months. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
