Verdict

The call

Scanner HD and PDF Scanner both sit at 4.8 stars, but that hides the real split: 100% of PDF Scanner's written reviews are positive against 54% of Scanner HD's. PDF Scanner also leads on ads (none vs shown). Scanner HD's advantage is update cadence (fortnightly vs every 4 months) and ratings volume (316 vs 50). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Scanner HD sells 3 in-app purchases, starting at $4.99 per 7 days and PDF Scanner sells 4 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Scanner HD holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Scanner HD has 316 ratings behind it against 50, so its average is the more settled of the two. Written reviews complicate that: 54% of Scanner HD's written reviews are positive against 100% of PDF Scanner's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Scanner HD ships an update fortnightly, PDF Scanner every 4 months. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
