Verdict
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.
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 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.
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.
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.
