Verdict

The call

The clearest difference is review sentiment: PDF Splitter + PDF Merge at 88% against PDF Expert's 46%. PDF Splitter + PDF Merge also leads on device support (4 vs 2) and iOS requirement (13.0 vs 16.0). PDF Expert's advantage is ratings volume (216K vs 139) and update cadence (fortnightly vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

PDF Expert holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: PDF Expert has 216K ratings behind it against 139, so its average is the more settled of the two. Written reviews complicate that: 88% of PDF Splitter + PDF Merge's written reviews are positive against 46% of PDF Expert's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

PDF Splitter + PDF Merge ships an update every 3 months, PDF Expert fortnightly. The most recent releases landed on September 23, 2026 and September 25, 2026 respectively.
