Verdict

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
