Verdict

The call

The clearest difference is ads: One Scan at none against PDF's shown. One Scan also leads on rating (4.7 vs 4.4) and ratings volume (12K vs 1.4K). PDF's advantage is review sentiment (60% vs 26%) and iOS requirement (15.0 vs 26.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. One Scan sells 10 in-app purchases, starting at $3.99 per 7 days and PDF sells 8 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

One Scan holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: One Scan has 12K ratings behind it against 1.4K, so its average is the more settled of the two. Written reviews complicate that: 26% of One Scan's written reviews are positive against 60% of PDF's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

One Scan ships an update every 2 months, PDF every 6 weeks. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
