Verdict
The clearest difference is ratings volume: PDF Expert at 216K against Prizmo › Document Scanner, OCR's 156. PDF Expert also leads on rating (4.7 vs 4.4) and update cadence (fortnightly vs every 6 weeks). On price, review sentiment, 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 Expert sells 10 in-app purchases, starting at $9.99 per month and Prizmo › Document Scanner, OCR sells 6 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
PDF Expert holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: PDF Expert has 216K ratings behind it against 156, so its average is the more settled of the two. Written reviews complicate that: 46% of PDF Expert's written reviews are positive against 54% of Prizmo › Document Scanner, OCR's, so the app with the better star average is not the one people write more warmly about.
PDF Expert ships an update fortnightly, Prizmo › Document Scanner, OCR every 6 weeks. The most recent releases landed on September 25, 2026 and September 22, 2026 respectively.
